MTN worst service provider

I paid my account on the 27/02 the full amount using the same reference ive used for two years, I then received a sms around the 03/03 informing me my account has not been paid. I called Mtn on the 03/03 to sort this and got nowhere, between then and now ive sent about six emails with proof of payment and a bank statement attached, ive created two queries on the mymtn website around the 13/03 to which ive received no reply. My services have been suspended for a week even-though ive asked Mtn not to suspend as they have not allocated the payment and I have not received my data or minutes so I guess im paying for no reason other than to be utterly annoyed and unreachable on a mobile phone. I posted this review on the 19th and was then rep**** to by Mtn with instructions to yet again send everything ive sent a bunch of times and yet again I have not been helped. I have now sent another 4 emails. Other then the fact that Mtn has been wasting my time and not providing me with the services im paying for im receiving threatening messages from Mtn.
