Absolutely infuriated

The Customer Service you get from Supersonic is absolutely pathetic, and quite clearly their billing department are clueless. AVOID THIS COMPANY AT ALL COSTS On the 19/01/2021 we received an email from a Vimbai Chakanetsa stating the account had an outstanding balance, a surprising prospect as the company pays this account together with other Supersonic accounts every month without fail. On the 27/01/2021 my accountant forwarded proof of payment of the account to Vimbai. There was no response to this from Supersonic so we sent a follow up email to Vimbai on the 29/01/2021. Still we have received no response from Supersonic. Then on the 09/02/2021 without warning, my internet services were suspended. I spent 2 hours on the phone (it takes at least 20 minutes just to get to speak to someone) attempting to get the matter resolved. After speaking to multiple operators that have absolutely no clue what they are doing or anything about customer service I was put through to Sihle Mngadi whilst also quite pathetic but marginally better than the rest, told me he would get the Supervisor, Shireen Govender to contact me shortly. As of 11H00 on the 10/02/2021 I am still waiting for this call. Efforts to contact the customer call center again have been fruitless and after waiting the normal 20 minutes to get to speak to someone they put the phone down on me. Needless to say I still have no service now jeopardising my relationship with my clients
