WebAfrica - Useless, unresponsive ISP

I have had issues with my fibre and have attempted to log a call for 2 days. This is serious to me as it is my business. When I eventually (after holding for 2 hours) spoke to a person and logged a call, NOTHING happened for a week. To date I still cannot get an answer. And I cannot cancel the service as their website has a bug and I cannot log a call.
