Bad experience with MTN

Good day. I would like to report a very bad experience with MTN. Firstly, my daughter lost a cellphone, and we were then taken from pillar to post with no proper assistance. In addition, my contract had already expired, and I did not upgrade it. I formally terminated the contract, yet MTN continued to deduct money from my bank account. After numerous phone calls and several visits to the MTN store at Rustenburg Waterfall Mall, the debit order was eventually stopped and my contract terminated. I was later informed that I had allegedly insured the SIM card and subscribed to local data, SMS, and voice services, which I am not aware of and never agreed to. This month, an amount of R1,629.00 was debited from my account without my consent or any agreement in place. I did not request or authorise any insurance or additional services, especially since the contract had already been terminated. ***
