Avoid MTN at all cost

I am at my wits end with MTN. I have received the worst service ever since my contract ended and I tried to cancel it. My contract ended in February 2022 and from there I was on what they refer to as a ‘month-to-month’ which I had no issues with. My SIM card then got lost in June 2022 and I requested a sim swap which was unsuccessful so I requested the ‘month-to-month’ to be cancelled. I have been billed for this cancelled contract every month since July. Every time I call the consultants they are rude and do not take a moment to listen properly to what the customer is saying. I’ve been sent from pillar to post whenever I try to resolve the issue, not to mention having the call being hung up on me several times. I don’t know what to do at this point because MTN is not concerned about their customer service and there aren’t reliable avenues that can be trusted for escalating this matter. I have been struggling with this since last year July. For your own peace of mind, I urge you refrain from being in affiliation with MTN in any regard. You will regret it.
