Yet again being ignore by MTN

Im really getting fed up. If you try contact MTN directly they are of no help, the only way is to complain via HelloPeter and only then do they respond. I have been in contact with Timothy Clouts, as I want to cancel my one contract that is coming to an end this month. He sent me the cancellation forms and told me to send it back to him with a copy of my ID by the end of January. Which I did on the 30th January. I then followed up with him yesterday 2nd February, and he has chosen to rather just ignore me. This is rather disturbing as I do not want to have this contract for another 2 years. Why do MTN employees refuse to do their jobs? Come on now, sort out your staffing issues!
