Bad support and service from WebAfrica

I upgraded my fibre line to a 20/20 July 2020 and I tested it and all was ok. Never had issues with my internet, but last week I tested the line speed again and saw that the line speed was 20/2. I got in contact with WebAfrica on their WhatsApp support last Thursday 28/01 and with plenty of transferring from one support agent to the next I eventually got refunded for 3 moths. Since this I have been trying to get the refund for the other 3 moths to no avail. I have been transferred so many times to other support agents on this WhatsApp support I lost count! It feels like this form of support is just an easy why to make client's issues disappear. This is turning out to be one of those issues where they are happy to take your money ad not care about the service afterwards. I must add that I have been with them for a while with no issues. This is the first time I really have struggled with them. But it is so bad that I am really thinking of going to another service provider. This WhatsApp support is more trouble than its worth because it feels like support agents just transfer you not to have to bother with your concern.
