The worst ISP provider! Biggest regret! *******!

I requested the services of Supersonic in the 2nd week of January. They came the following week and it took them two weeks to install the device problem 1. Problem 2 they then bill me two weeks worth of their air fibre and I had not used it during that two weeks as their technicians were using it to test if the signal was strong. I called in and told them about this then they told me they will escalate it to the billing department, this was in Feb we are now in March I have not received any communication from them regarding this. Problem 3, in Feb they billed me twice sending separate invoices, when I checked my bank statements they had debited an amount I had not signed up for which was R599, yet I was billed twice that R599x2 it appeared as though the error was in fact on their end and they created two accounts for me billing me twice. I called and I had asked them to resolve this, they told me they would escalate it to the billing department. No response again. Problem 4, end of Feb to beginning of March they billed me twice again and added change around R400 more I called In livid asked to speak to their manager I was put on hold for close to 40 mins they came back and told me a manager was not available and that the manager would call me back( this has not happened again they were also going to escalate to billing no response or feedback again). I have gone as far as trying to call almost everyday no response or the customer agent is just plainly not interested. Further, as I was laying out my grievance to one of the agents they hung up on me as I was talking I called back and no answer. I have been patient with them to downright angry as I have never come across a business that has no respect for it’s customers and their money. Problem 5, we are now in April, the invoice came in again and I was billed twice. This most heartbreaking part about this month is that the invoice read R1198 yet when I checked my debit order from supersonic R2656.53 came right out of my bank account, so on top of the fact that the contractual agreement I had entered with them was for R599 this month alone I was charged an additional R1963.53. To make matters in even worse I called in and asked for their complaints procedure and they told me to write my complaint on a Hello Peter, Or Twitter. Hello Peter and Twitter are great platforms to help raise consumer awareness about what they might be getting themselves into when they use goods and services, but for a company to teach or inform their employees to tell their clients to go to Hello Peter and complain was jaw dropping. The worst company I have ever decided to spend my hard earned money on in my entire life. I am now forced to go to the bank and dispute this debit order and the one in March as I have a budget to maintain, yet Supersonic has resolved to *****ing their clients hard earned money. An absolute disgrace. If you are reading this with all due respect save yourself and your bank account. I wish I had. I am in tears writing this as I again have never come across a company that disrespects their customers like supersonic. At the end of April I am canceling my contract with them. I want nothing more to do with them!
