Mtn - customer pay in full even if no wifi

I understand that you have issues in providing proper wifi MTN, I've been struggling for a while and currently I have no wifi and I had to buy data. Although I understand your problems and have sympathy with your position, I dont see you reducing the R1000 I pay every month or reimbursing the data I just bought.Please explain to me why I currently have no fibre but you still take the full amount?
