Frustrated Customer

I have had thee most painful experience with MTN, I have been cancelling one of my contracts for 3 whole months,I called in and it seems like your consultants do not want to help me or they are ***********.I expressed my concerns on twitter but apparently MTN is unable to trace if my account was accessed. Only one of your consultant could pick up that Cresta Branch tried to close it in AUGUST!. We are October and I am still fighting the same battle. Why is it difficult to action this request? Is there a person who is capable of cancelling a contract that has long expired. Your consultants are extremely RUDE too. A Nikita made it clear that shes doing me a favor for calling me for a request you failed to action.
