No Service: Contract Cancellation

MTN provides absolutely horible customer service. I have been trying to cancel my MTN mobile contract with them for over a month. If I go into the shop they simply tell me they cannot do cancellations in store and I have to phone the 808 helpline. When I phone the helpline there is simply no answer. I have phoned the helpline three times to cancel the call and no-one answers. I have sent an email to the custumer care email address to cancel the contract twice aswell and have received no reply.

Then I received a call from one of there employees to upgrade my contract. The woman was rude with me on the phone and when I told her I am not interested in upgrading the account she rudely asked me what the problem is. I told her I want to cancel the contract and asked her if she could help me or transfer me someone who can. She responded that she cannot help me because she works in the upgrade department and then hung up the phone.
