MTN customer service

Hi Good day , In April/May I paid my account via internet banking but I didn't put in any reference numbers. In June I found that mtn sent me an overdue account notification. So I went to the bank and to various mtn stores to try and sort out my query. I paid R1500 in total INTO their account with their account details as per my statement.

Every since then I've either been cut off saying that I owe them money (which I actually don't). They have given me email addresses to mail my query to but nobody makes any contact . I've only received an email to say that they've received my query but nobody has made any contact or tried to solve my problem. R1500 isn't money that's laying around. I've worked my ass off for that money. Now they won't even refund or allocate the fund to my name.

I don't want emails to be sent, I want a real person to handle my query or what does customer service actually mean to Mtn?
