Account canceled without consent

I have had my home wifi with MTN for the last year. Yesterday I even paid for a booster on my account to increase the speed. Today I wake to an sms saying that I canceled my contract and that I have been moved to prepaid.

I called the call center and I went in store to try and resolve this issue but firstly the call center takes at least 30 minutes before you actually speak to a consultant then when you go in they say there's nothing they can do but log a case of *****. I got told the best solution is to take out a new package which means paying again for this month plus the upfront fee for the next month. There's nothing they can do about the money spent already but hope that the accounts team credits me for the balance of the month and what I spent yesterday.

Watch me take this up with the ombudsman if I do not get a response from them by tomorrow as promised.
