********** accounts made to be customers problem

I received a R14,000.00 bill from MTN and called to advise that 3 additional ********** accounts had been added to my profile. I was then told it was my responsibility to write an affidavit and get it stamped at the police station and bring it in to MTN. Not only did this waste my time, when MTN loaded the ********** accounts but became my problem to sort out. I duly did as requested and proceeded to MTN to stop the debit order. I was promised by the MTN representative that this debit order would not go off at the end of October as it was only the 23 October and they would sort it out. True to form, the debit order went off and I returned to MTN again to be assisted by Neo Peete who promised to contact me with regards to the reversal of this debit arder. Again nothing happened and I managed to contact my bank who reversed the amount. However, then I received a R25,000.00 bill at the end of November. Again, I followed the same procedure going in and saw Pinda the manager and was told it won't be debited, however it was. Today I went back and saw James the manager, who said he will rectify, but I have little faith in him.All my debited orders have now bounced, so who pays these cost?
