Early Termination from Heaven not me !

Good Day, October 2017 I was told , Im deceased by MTN and my number was taken off the network, I had to do all sorts of stuff to proof that I'm alive (affidavit.. etc), eventually after weeks it got sorted, now the following month of November 2017 a bill of approx 4-5k was invoiced, and I queried it only to find out that "they saying I have filed for early termination" which I never did, to date my line its blocked with an outstanding amount that came from the early termination from heaven.... I have spoken to half of the consultant at MTN, they keep escalating the matter to legal, Legal has not responded till to date, only last week I spoke to a consultant (Jacob) and he advised that this is not a legal matter but a Billing department problem ... ........ I just called MTN 5min ago they saying the account should be escalated to Retention Department .... , pillar to post approach , who actually need to just look at my account that is up to date and fix my account and re-open my line ... This is so annoying ! Worst Service Ever ...
