MTN South Africa, poor customer service!

A migration was done on my contract without my consent which resulted in an increase in my monthly subscription by more that 100%.

I contacted customer care over 10 times and the issue is not yet resolved.

The service team champions are useless and they can't seem to assist besides creating tickets and telling me to wait 2 to 3 business days. It's being over a week and the issue still isn't resolved.

I cannot wait for my contract to be over with MTN, their service with resolving issues are pathetic especially when this could be something ********** that was done to my contract without my consent.
