Stay away from Supersonic, you will regret it.

I am having the worst experience with Supersonic. If you want to change service providers do not consider Supersonic, you will regret it.

I have been experiencing connectivity issues since Aug 2025. I am constantly calling Supersonic to fix the issue, every time they would say they can see the issue and will send a technician. I would sit without data waiting for the technician, 2 days later when I call to enquire as to when will the technician come, they say they have cancelled the ticket because I have data. They have been doing this till today. That time no one phoned to check on me, they just cancel the ticket. I am always buying data from another service provider to connect using my cellphone. However; every month without fail they debit my account. So I am paying for data that I can't use and buy from another service provider to use on my phone. The sad part is 90% of the time I work from home.

I ended up cancelling their services in Sep which they told be I must serve a month's notice which I did in Oct. Around the 20th Oct I get a call from their customer retention agent trying to convince me to stay, I said no. He then says they will charge me R2500 for cancellation. When I ask him what is it for because I have been with Supersonic since Jan 2023. He says it's an instruction from the accounts department.

I have been calling them almost everyday to resolve this but the consultants keep saying they have escalated the query. On 1st Nov they debited my account with R2500. To this day I am still fighting to get my money back.
