Debit order

I had a contract with MTN for my mom's phone. In May when I asked them to cancel the contract I was then told that she first had to finish the airtime or else she would forfeit the R205.00 she had on her phone then.<br> Even then I only got a proper response after reporting them to this website. ref number ***.<br> <br> I was told to give them before the 20th of any month as the contract date was on 20th of each month.<br> my mom gave them a call on 17 Sep and she forfeited the R12.00 airtime she had as agreed.<br> and there was a follow up call for cancelation just to confirm everything. on the 20th R100.00 airtime was credited to her cell phone and later it was taken back by MTN.<br> <br> To my surprise on the 25th Sep R145.00 was taken from my account and since the first week of October I have been trying to get clarity on how my money was taken for nothing! still today I don't have any answer- the last time I sent them an email was on 21 Oct ref number ***6.<br> <br> I now know that the only communication that they understand is through this website.<br> all I want is my money back, I can not to billed for airtime that we didn't use! please help
