I want my money back

My contract with MTN expired early this year.<br> I subsequently called the call center to conclude the account (converting the account to a prepaid number) and realized that I had been overcharged for a number of months. I was informed that i would have to wait a month in order to claim back my money from MTN. <br> After numerous attempts to get a hold of someone who could assist me a month later i logged a request to get my money back. <br> It has been about 2 months and I have not heard anything from anyone regarding my refund. <br> <br> I would like some feedback...<br> <br> <br> Reference Number: 132 009 525<br> <br> Cell Phone Number ***<br> <br> Account Number A***<br>
