Don't waste your time. Unreliable.
Unreliable, empty promises and no urgency. A joke of a ISP, they had the audacity to bill me while my internet services aren't working. Till this day nothing has been fixed but they swear up and down that it's working. Zero communication, still waiting for Saaid to contact me back, empty promises from someone I thought would actually be able to assist. Don't waste your time with these people, they make empty promises. An absolute letdown.

Pathetic, unreliable, empty promises
Just a super let down. After my complaint I was contacted by Saaid again. More promoses were made and till date nothing was actioned as usual. The most unreliable service you can imagine, a company that takes no responsibility for their actions at all.

Very very bad experience
I signed for this WIFI and paid the required installation and service fees upfront. The technician came instaled the router on Thursday and connected everything but 24 hrs later we experienced connectivity challenges, logged a a call and we never got assistance, we basically paid for service we never received, it's Friday now and still haven't received support, they dont call us but we call them everyday and we are told the same thing "your issue has been assigned to a technician". I don't have words to describe how terrible this company is.

Worst ISP Experience EVER!!!
I signed up for Supersonic Air Fibre and paid R600 upfront, which included the full installation fee. An installation date was arranged and confirmed, but nobody showed up—no warning, no explanation, and no update from their side. I had to initiate contact myself just to inform Supersonic that their installation team never arrived. Since then, it has been a complete nightmare of poor service and endless excuses: Shifting Responsibility: Supersonic keeps blaming MTN for the failed installation, while MTN has explicitly stated that Supersonic is responsible for resolving the issue. Refusal to Assist & Ignored Calls: My assigned consultant, Monica, has been completely unhelpful, displays zero accountability, and has now resort to ignoring my phone calls altogether. I paid upfront for a service that was not delivered, and instead of taking ownership to get me connected, Supersonic has completely abandoned customer support. I strongly regret not reading reviews before signing up with this company. If I could give zero stars, I would. Desired Outcome: Immediate escalation by senior management to either complete the installation within 24 hours

Absolute administrative *****: Confirmed my downgrade in writing, kept billing R899, and handed me over!
Supersonic's level of incompetence, dishonesty, and administrative chaos is completely staggering. On 1 March, I formally requested a downgrade of my Uncapped Fixed-LTE Premium service (R899 p/m) to their 120GB Fixed-LTE service at R279 per month. I explicitly explained that I would not be at the property for the next few months. Rather than cancelling the line outright, I purposely chose to downgrade and keep a minimal package running while away so that the service would remain active for when I returned. On 11 March, I received official written confirmation directly from *** stating in black and white: "We have completed your request to downgrade...". Despite having their explicit confirmation in hand, Supersonic completely failed to process it on their backend systems. They *******ly kept billing me at the old R899 rate for a service I wasn't even using and hadn't agreed to pay for. When I refused to pay for their systemic gross negligence, instead of correcting their own glaring mistake, they had the absolute audacity to sic debt collectors—Shapiro Shaik Defries & Associates—on me for R1,690! You confirm a downgrade in writing, fail to do your jobs, ignore your clients while they are away, and then try to bully them into paying for your own system errors? I have attempted to follow up on numerous occasions with Supersonic and given them every opportunity to do what is right and correct this billing nightmare, but they just ignore and close tickets. Absolute disregard for customer service. This is *********, predatory, and pathetic business practice. Recall this ******** handover immediately, correct my billing to the R279 package that was confirmed, or I will take this straight to the ISPA and the National Consumer Commission. Avoid Supersonic like the plague!

SUPersonic ISP & MTN FIBRE – AN ABSOLUTE DISGRACE! TERRIBLE CUSTOMER SERVICE AND ONE EXCUSE AFTER ANOTHER!
I honestly cannot express how disappointed, frustrated and angry I am with the absolutely appalling service I have received from Supersonic ISP. As a NEW customer, I expected a professional service, a reasonable installation timeframe and, at the very least, people who actually care about assisting customers. Instead, I have been met with a complete lack of interest, endless installation delays, broken promises and a different story every single time I pick up the phone. Quite frankly, if I had known what I was getting myself into, I would have RUN in the opposite direction! How does a company expect to attract and retain customers when it cannot even deliver on the most basic of commitments? Every phone call brings another excuse, another promise and another disappointment. Where is the accountability? Where is the customer service? And where is management when customers are left chasing their own installations? Let me make one thing absolutely clear: **this is no longer just about a delayed router. It is about the complete lack of professionalism, accountability and respect shown towards a paying customer.** I intend escalating this matter to ICASA and lodging the appropriate formal complaints regarding the conduct and potential consumer protection violations involved. I also happen to have a direct professional connection to ICASA, which makes me particularly determined to ensure that this matter receives the attention it deserves. I would also like to understand how MTN Fibre and Supersonic ISP are being held accountable for their customer service practices and whether the relevant consumer protection authorities are aware of the experiences customers are having. I am not interested in another scripted apology or another empty promise. I WANT MY ROUTER DELIVERED TODAY! Furthermore, I expect a telephone call from a manager or someone in senior management who has the authority to take ownership of this situation and provide a definitive resolution. I deeply regret choosing Supersonic ISP. Fortunately, I can change providers after my contractual month, but that does not mean I intend to simply walk away and forget how this matter has been handled. I will pursue the appropriate complaint and escalation channels until I receive a satisfactory response. **A GENTLE REMINDER TO MTN FIBRE AND SUPERSONIC ISP:** A delayed router and poor communication could have been resolved with one honest conversation and proper customer service. Instead, your handling of this matter has escalated what should have been a simple installation into a much bigger customer relations and accountability issue. You had an opportunity to make a good first impression with a new customer. You have spectacularly failed. **SORT THIS OUT. DELIVER MY ROUTER. AND HAVE A SENIOR MANAGER CONTACT ME TODAY!** I would strongly advise anyone considering Supersonic ISP to think twice and do their homework before signing up.

******** WITH NON EXISTING CUSTOMER SUPPORT!!!
Absolute shocking experience with supersonic ISP. Their customer service is none existent. I placed an order with them which they cancelled however they never cancelled with Vumatel. Now my new isp cannot activate my line as supersonic has placed a hold on the line and not cancelled it when the order was cancelled. Preventing me from activating my fiber line and cisting me income. I am a single mom to a severely autistic child and need this resolved immediately. Over 48 hours of emails begging for help. Being ignored on whatsapp and emails for over 48 hours. I am taking legal actuon for loss of income and cinracted the ombudsman. I never had a contract with them and they are just blocking my line. Vumatel cannot do anything till they fix this.
