Mtn SA is the worst.

It's been almost a year now pleading with MTN to cancel my contract with them. They close it for few months then re-open it again without my consent. My contract with them ended on the 28 December 2019,contacted their customers services and confirmed Ref *** but still shows I'm owing R18. I regret the day I decided to do business with MTN. Their services is pathetic. I'm tired of having to go back to them every 3 months about the samething
