Poor delivery service

I called castomercare & spoke to n blackman. I asked him why my accountbalance is so high. He told me that my debit order didnt go through on the end of October. I asked why not. He cant help me. My account is every month less than R870. But because they didnt distract the money end Okt they charged me end November over R2100. I whant to know why because 2 months still is not even R1800.<br> <br> I called again and talk to a lady that tell me must go & paid R1200 into MTN's bankaccount because the debidorder cant be chainged. So because I dont have it I pay them R1000. But then they deduct the money also via debitorder.<br> <br> I call then MTN headoffice. Asked to talk to the manager. Switsboard put me throu to Pheola. I told her the whole story. She said I am in credit with R950. I asked this lady to pay my mony back because we must buy food with it. She told me it will take 7 to 14 working days. Is unacceptable. That was not the agreement. And why is my account so heigh...they cant answer me. Pheola is very rude. Im still busy talking to her then se put me on hold. We dont have any money in our account becaese of that money that they take via debitorder after I pay the money into bankaccount.
