Still no resolution

I have not heard another word from MTN, as usual they are ignoring me and then they just go ahead and debit my account. Is there nobody that holds these service providers accountable? Why are they allowed to just take money out of ones account and no matter how many times you contact them they just do absolutely nothing about it. I have been trying for 3 months now to stop them from debiting my account and the contract has been cancelled for 4 months but I cant seem to win. WHAT ELSE CAN I DO? If my account gets debited again on the 1st of January and I don't get refunded my R237 soon, then perhaps a story in the paper will help. Maybe they must ne named and shamed for their incompetence.
