Incorrect billing

After two month of trying, countless reference numbers and MTN acknowledgment of a billing mistake...u deducted over R700 more out of my account end April. This month instead if the normal R977, u tried *****ing R3727 from my account. I stopped payment as i will not allow the ***** to continue. I will arrange the normal payment of R977 but i want my ****** R700 from last month refunded to me and my bill corrected. Pls stop feeding me lies and get someone to contact me as i can not get hold of someone since ur strike started. Im beyond upset but i want to believe that u will be able to resolve this matter soon as so many people here on Hello Peter have been de*****ed in this way. It is clear that MTN has one serious problem and I am not refering to the ongoing strike. Pls stop updating ur FAcebook page so regularly and rather tend to all these billing problems as you are loosing ur customers in drones. Start giving a **** about ur so called \valued customers"im awaiting ur call."""
