Over a year MTN has ignored two cancellations and continues to bill me

<p>I first cancelled my account in May 2015. I was told the early cancellation fee would come off my account automatically the next month... it didn't. I then tried to resolve this and eventually gave up and simply attempted to cancel again in September 2015. This time they created a retention note and asked me to pay the early cancellation fee immediately. I paid the fee, it reflected on my account but they ignored it, did not cancel my account and continued to bill me. Since the end of last year I have created many support requests, most ignored. Occasionally when a query is answered they simply ignore my request and tell me to pay my arrears account before I can cancel again. I vented on Twitter a few months ago and quickly got a response... and then nothing was done again. I got the "legal team" involved, but they are just as useless as the general support team. I don't know what to do any more as no one senior seems to be monitoring exceptionally long support queries.</p>
