MTN *****ING FROM THE PUBLIC

I've had the worst experience with MTN. I took out a combo contract for a laptop and wifi modem in 2021. The laptop was faulty, and the wifi modem never had signal. I then went in-store to cancel the contract around June 2023. In order to cancel it, I had to pay R3906. My bank account is still being debited for the modem contract and the customer service is pathetic! You have to go through a 100 different people and in-store staff will or cannot help you. Still nothing is resolved. According to MTN it wasn't canceled because I didn't phone "retentions". ***? Why did I have to pay almost R4k in-store to cancel a contract that can't be canceled in-store????? MTN's processes are useless or the staff are just all ***********! I HAVE BEEN PAYING FOR A PRODUCT THAT I HAVEN'T BEEN USING SINCE THE DAY I THOUGHT I CANCELED AS I PAID UP THE CONTRACT. MTN HAS BEEN *****ING FROM ME!
