Zero support and slow to zero internet from my ISP

I'm not being shaped. I'm not being throttled. From what I've been told, the account I have with Web Africa (uncapped 2Mbps) is looking good. But I get periods of no internet and periods of excruciatingly slow internet randomly occurring, every day. Internet just drops all the time. I had a Telkom technician check the line and send the test results - it's fine. I tested the router at Telkom - it's fine. Not only have Webafrica failed to follow up or provide me with a suitable answer (\I'm not sure"isn't good enough) but I'm quite obviously experiencing problems with my internet and they don't seem to care as long as I'm paying. Testing accounts with other ISPs currently to see if the line drops and it's looking better on the other side to be honest."""
