Cancellation Nightmare with MWeb

I have tried to cancel my Wifi subscription last month, but have to keep listen to the stupid music recording, and my movement in the line, wasting all my airtime to try and get through. I started as number 63 in line. Eventually gave up. I tried the chat line, and have to wait for about 40 minutes to get connected to a consultant who can help me. Eventually chatted to a consultant, who took all my information, only to hear that she will put me through to the retentions dept. I had to wait in line again. Eventually gave up, and had to pay another month's premium because I could not cancel with the 30 days notice that is required. Yesterday, I tried again! Same! I keep holding on for eternity. I am employed, just like them, and I am sure, had they have to cancel their subscription and had to be on the phone the amount of time that I, and other customers have to hold on, to do basic things, like cancel, their employer would not like that either. Today is the 2nd, and I can guarantee you, if I try to cancel today, they will still tell me that I am now too late to cancel for this month. So I would end up paying for another month on my subscription. Why don't they employ more people to manage the call center? I have to chat to a consultant because my business hosting is with them as well, and if I cancel any other way, they might end up cancelling my hosting as well.
