MTN ********ly suspends my longstanding contract

My contract was suspended due to an error on MTN's side. I am an executor in a deceased estate and act in my capacity as a nominee of a trust company. <br> <br> We sent through a request for a cancellation on a deceased client's contract, and included the death certificate as well as a copy of the Letter of Executorship. Due to an error in your office, the contract that was cancelled was my contract instead of the deceased persons contract. <br> <br> I have made numerous efforts to contact your call centre, however the phone is either not answered, or answered by *********** and unfriendly staff who clearly don't care about their customers. Yesterday I managed to speak to a supervisor (Linda) who promised me that she would send an email requesting the reactivation of my number. Needless to say, this didn't happen.<br> <br> The attitude of the call centre staff, if I can get hold of them, is unfriendly, unhelpful and totally ***********.
