Pathetic customer service

I signed with Webafrica in August as they were thebonly service provider in the complex we moved in. They used Teralink as Fibre provider. After more than 6 weeks of troubkeshooting, they could not provide the speed I app**** for and I requested they backbill my account to the speed that they could provide. Nothing happened. We moved in November and the fibre provider changed to OpenServe, which I thought would resolve my issues. After the move I found out the speed issue was never logged at Teralink by WebAfrica and hence the reason I never had feedback on my request to downgrade my account. I got my first bill after the move and it was an exorbitant amount. With the move I signed up for a 50up/25down line on their special that give you 200/100 FREE for the first 3 months. Since the special, I did not think much of the e-mail stating I am getting a 200/100 line. But then I was not only charged for the line, but also way more. It is impossible to get through on their phone lines, they just refer to their WA chatline. But I have been on the line for a week now, taking ages to be transferred to an agent. Once I get to an agent, they either read it and say I need to be transferred to someone else or they say they are reviewing my account and then the line goes inactive. This whole process just keeps on repeating itself. After 7 days of this and not even and indication that it is being resilved I am really fedup.
