Closed account

I have had a contract with MTN for as long as i could remeber. After falling in arrears with my account I have managed to settle the account this year to an amount of R 10***. Paying my account means that now I have to make sure from MTN that indeed they have received my money and that my account needs to be closed. But to verify of my account has indeed been closed(or at least I think it is) this seems to be a complicated story. I have called 808 and they took my details saying they will e-mail me my proof that my account is closed. This has not yet happened. I then e-mailed customer care at mtn where I got a reference number #1(e.g) and they e-mailed me back saying I needed to complete my details on their mail in order for them to check, this was done by me. I then inquired again via e-mail asking for updated and two weeks later I got a response from their legal department with reference #2 saying that my account has been handed over to DCCM( I still have no idea who this is) and a contact number was given to me which is ********** 000 which I then got to Direct channel Holdings and they told me to call ********** 093 and then they told me to call 808. So can someone please tell me where on this good earth am I supposed to get one piece of paper saying my account is closed because it seems I am going around in circles, thanks so much for that MTN

This sucks, and I want feedback
