Stop Debit Order***)

Good day, <br> <br> I had a cellphone contract with MTN that ended on the 27th of November 2015; called them a month prior to end date to terminate the contract and again on the 28th of November. I followed up with them to cancel the contract and move me to prepaid as contract ended and only in January 2016 my status was changed to prepaid.<br> <br> Days later I ported to another network but they still debiting my account and tried to bring up the matter to them but since my number is no longer under MTN this has been a tiring exercise. <br> <br> <br> Thanks,<br> Simson Moleleki
