No joy after 5 months of trying to upgrade or cancel my account

After receiving several years of communication from MTN to upgrade my phone, I finally decided to do so. After 5 months of attempting to perform the upgrade and 4 attempts to cancel my account, MTN have not made any communication even though reference numbers have been received. Their customer service is the worst I’ve ever experienced and never in my life have I spent so much time( over 12 hours telephonically and 3 hours at a store) to try to simply cancel an account.

I’ve already moved to a new service provider who answers their customer calls within less than a minute versus waiting for over half an hour per call to get a person on the line with MTN

Will never recommend MTN
