Unfair treatment by MTN South Africa

Good Afternoon,

I have been unfairly treated by MTN after I had a contract with them up to 7 years. I was never in arrears. In August this year my contract ended then upon discovering they are deducting 3 times my bill I called them in September to cancel my relationship with them. Then in October 15th mtn deducted R2400 and something from my account. After the deduction I called mtn again only to be told my contract is not cancelled. I repeated the same request of cancellation. In November 16th Mtn deducted again another R2 000 plus from my account. For what reason?....no explanation..I called and called the call center up to 7 times repeating the same process again and again!!!. One of the call center people dropped the phone in my ear trying to explain myself and the challenge about the unfair treatment of mtn. I spoke to someone in the billing dept and the person said it is cancelled. All of a sudden in December Mtn is deducted R2400 plus from my account again!!!!.......Then I reversed it. Now they send me an email saying I am owing them. What am I owing? Instead they should reimburse me with the money they deducted. 7yrs no arrears yet they treated me this. I have discovered they dont care about their customers, all they care about is money. They didn't send me an email when my account was about to expire. But now they know my email address when they are looking for their money. This is amazing. Please if there is anyone that knows a place I can report my situation with mtn should call me/whatsapp at ***. My concern is my credit score is being affected by their carelessness.
