MWEB client service sucks

This started off as a good relationship with MWEB, but is rapidly deteriorating. The line is fine, so far, but there are some issues. 1. I signed up for R399/month, 10 up, 5 down. Within 2 months, they increased the fee to R449/month. 2. Then within another 2 months, they increased to R499/month. They give bigger bandwidth (25/25), but I don't need or want that, was quite happy with my 10/5. 3. Called their call center, went through a whole rigmarole of confirming who I was, just to be told by a voice message that "due to unforeseen circumstances they cannot take my call", and call was terminated. ***? 4. I see here on hellopeter that they do not even reply to these messages.
