Worst experience with an isp

I highly highly recommend you avoid dealing with supersonic. They actually managed to reach worse service standards then telkom. I have been with them since December 2019 and have not stopped having issues. Double charged several times. Not getting required credit, services agents not getting back to me. June will be my last Month as I have R800 credit (supposedly, we will see if they double charge again in which case I will go to consumers council and report them). Other then the **** service, the technicians don't know a thing about their own network. I complain about jitter and latency and their respons is always "your speed is fine". Yes my speed is fine when the internet works but that's not my complaint. Latency to local services eg cape Town, which is in my province is over 100ms. I know people who get the same latency to foreign countries... Avoid
