WebAfrica - No1 in poor customer service - *********

I have been with Webafrica for a long time. Then during 2024 I had so many issues with constant slow speed and disconnecting. I kept contacting them via the WhatsApp platform. Every time they assured me that the issue was resolved. Then when I got irritated and asked them for refund for all the downtime, they said there were no tickets logged. I went to the website to try and log tickets, but you cannot log a ticket. This is a very clever way to not keep any reference with regards to issues. You only have your WhatsApp messages, which I send them, and they still denied it. I was forced to cancel my service with them in December. I then paid December and January 2025. Now they still want to charge me R999 for canceling after such poor service. How do I resolve this. It is not about the R999, it is a principle.
