MTN is not reliable anymore

when I called to get the balance I was told I owing R560 and you cannot debit R2690 without prior arrangement with the customer. I called in to make payment arrangements and the amount I was given was R560. MTN does not and will not have a right to debit an account of client an amount that was not in agreement, please trace my account from when all this started and I have been paying with no hick up in between, I have spoken to several consultants on 808 who have made requests to Legal department to give a call in which non of them was made to me.<br> The last scandal you had with your call center in August was a disaster which set my record backwards in sorts of nonsense and the Legal team was no where to be found. If MTN continues to do business like I foresee a loss of clients and downfall of revenue here in South Africa. The amount of airtime and I have spent on my phone, company phone and on the computer ,equates to the amount of money MTN suggests I owe them. May I please have a final arrangement with you guys about this matter because I think there are other several Service providers who will be glad to render me service that is on a higher standard than this.<br>
