sick and tired of mtn

I have requested for my contract to be terminated for months now and i am not pleased with mtn service at all. I can't allow you to continue debit me for no reason at all. I will be cancelling my mtn number and ill move to another network. I will be cancelling your debit oders on my account so do not expect me to pay for no reason at all. I tried to call call centre buy to my surprise it is closed. This is my last resort and I definitely do not want anything to do with mtn. So you might as well just cancel the line! I know that writing on hello peter doesn't help since you only know how to reply and make false promises. I have been waiting for mtn to contact me from the 27th of may but I have realised that its better for me to just cancel my mtn number! R850 is a lot of money id rather put it in my savings account for rainy days! I curse the day I took cellphones on contract and most especially with mtn!
