MTN *****ing Money

I have logged several complaints, sent emails, tried to call and nobody has assisted me! MTN has taken money off of my account for 3 months after my contract has expired. I gave them 2 months notice, as requested, to cancel my contract yet they still debited my account for 3 months. They have finally converted the number to prepaid but lets see if they still debit my account. I still need to be refunded for the 3 months that was incorrectly debited. I expect this to be sorted as it is now 4 months later and nothing has happened!!!!! I expect to get a call or at least an email after this to sort this out or even just a correct process of sorting this out. MTN is absolutely useless!!!
