USELESS ACCOUNT CLOSURE PROCESS

I have since settled my MTN contract and requested the account terminated and this was in November 2015. I called the call centre several times and was advised this is being processed. In January I got an email that my request has been received and I will be advised when account closed. Its march now and when I downloaded my credit report I see MTN is still showing and when I app**** for credit MTN was one of my financial agreements. I called the call centre which is useless cause I just got transferred from one agent to another without any reason. The agents are so rude and don't even know good customer service as they don't even greet nor tell you why they transfer you. I am so annoyed by MTN at this point. The last agent I spoke to told me they don't have account closure letters. What useless SERVICE!!!
