Pay back the Money!!!

It was an absolute mission to close my MTN cell contract. While struggling for months to get it closed I dutifully paid the account every month. It came about that I finally received my updated final statement and found that I in fact paid an amount of R562.47 too much. I contacted the call centre on the 26th of August and was assured that I will be reimbursed within 7-14 working days. (Ref ***)<br> <br> Now more than 2 months later I still have not been reimbursed. You phone the call centre number but you just cant get through. I have sent numerous mails asking for someone to contact me to get this resolved..<br> <br> Please just pay back what is owed to me
