OVERCHARGE- PSD

Hi! Sir<br> I am really disappointed with MTN's new PSD charges on my internet contract. My internet contract(2gigs) from a R99 a month has gone up to R1557 a month. I have requested the URL report from MTN which was only sent once I complaint to your office. After viewing it I see that MTN started to overcharge me as from December 2014. I have reqeusted them to rectify this account so that I can make payment, but as usual they send you the bill without rectifying the account. Now they have disconnected my service and threaten to hand over my acc. I dont have a problem to pay the account but how can I pay a service provider if they continue to rob people. When you ask them to assist there dont even understand the PSD charges, one will tell you I am exceeding the 2 gigs, one is telling me its the new billing system, and another is telling me I am using my internet to make phone calls.<br> It will appreciated if your can please me, cause to get assistance from MTN it is a problem. I would really like MTN to please check my account urgently and correct it, so that I can pay this account. I have been a customer of MTN for the last ten years and never had such a problem.<br> <br> Kind RegarRitesh
