MTN contract cancellation nightmare

Contract termination nightmare. Even after my previous complaints, MTN has a zero care attitude towards the CPA, law and Clients specific requests. I constantly asked for my contract to be terminated, which is the biggest nightmare one can have with the network. You wait for two hours, only to be told that they must transfer you to another department who also cannot help. Once I terminated my contract, I asked specifically to be switched to prepaid. After all the trouble, eventually MTN agreed to ending my contract and switching me to prepaid, I find out at the end of my term that they have switched me to a month to month contract. Im unbelievably agrieved by the way in which they conduct their underhanded business. I could not have been more specific in my request to cancel my contract and to switch to prepaid.
