*********** Staff and most pathetic service

I have a contract with MTN and there are 4 numbers on this contract. Two of the numbers are on on My MTN Zero and one number contract has ended on end of September. I have been trying to contact customer service, cancellations and retention department but without success as I made numerous calls (lost count of the calls), held on for 20-37 minutes for the call to be answered, explained to the consultant to stop billing me for the number where the contract had ended, I would then be transferred to cancellations and then the call disconnects. I have numerous e-mails but not success. I am a cash paying customer and bother the numbers that I had would add up to R964 but the bill would always be doubled around R1980 so when I did ask a customer service consultant of the amount I was told that I was billed for two months at one time so when I did pay the amount that I was supposed to pay (cash customers must pay by the 17th of the month...this I was told my a consultant)...who gets paid on the 17th of the month?) then the numbers of the contract gets blocked because two months payment had not been made. I questioned this and the consultant could not explain I get billed for two months at once and if not paid my account gets blocked. My one contact number as ended September and I am still being asked to pay for it. I have one number that is still on contract and I will only pay for that number which is R575 per month, not two months so please correct your systems and stop blocking my account as the account in in errors. PLEASE.
