unfair

I've been and MTN customer for 15 years and Im very disappointed with their service. Last year towards the end of my data contract term (march/April) I opted for an upgrade to a my call 100 samsung S5 at the bank city branch. <br> <br> I was told they are currently out of stock, then I was billed and extra amount month end, I went to the branch, they refunded me a and explained the account was already migrated to the new plan. Second month the debit went through again,I reversed it and went to the branch, they called their accounts department and I was assured that this will wont happen again, I immediately cancelled the new contract and asked for my number to be turned into pre-paid. Third month my number was on prepaid, but was debited again, I then reversed the debit again and never bothered to go to the branch since I was no longer based in town.<br> <br> I received call from VVM lat week informing me that I've been listed at ITC and they are handling collection for MTN. I told them the story and that I've never recieved a handset, they said I should send them and affidavit and will try to help.
