Terrible service from MTN South Africa

What an appalling service I received from MTN South Africa. I signed a router contract over the phone in February 2022. The sales person gave me incorrect information which led me to sign the contract. When the router was delivered, I opted to cancel the contract within 2 days of receiving the router even before I could open the package and ask for Sim activation. That was within the 7 days cooling off period when you are allowed to cancel the contract without penalties. To my surprise I discovered that MTN was debuting my account almost R700 for the same canceled contract from February until now. I wrote emails to MTN, made phone calls asking MTN to refund my money since they have been debiting me for a canceled contract and for services I never received as I returned the router to the MTN store unopened in its original packaging but they are sending me from pillar to post. No one wants to take responsibility. I am made to hold on the line for 15 minutes or more and they end up dropping the calls on me.

What a shame MTN SA
