My line suspended!!!!!!

I upgraded in August, got an incorrect amount going off my debit order. I called MTN to verify and get a breakdown and was given stories and attitude, I was then told to refer my dispute to Hellopeter!!! I made it clear that I will not continue paying until the matter was resolved. My line has since been suspended, I cannot even call MTN to resolve the matter and the 083 808 number is INVALID. I also sent am email to [Email Removed] and have not received any feedback. How then can we resolve this matter if we cannot even communicate??<br> <br> Can someone from MTN please contact me, I don't know how and assist in resolving this matter.<br> <br> PLEASE!!!<br>
