BAD CUSTOMER SERVICES

I had requested that my contract be cancelled as soon as the contract expires. I had requested this in February 2015. They have not done this. Debit orders continue to go off my bank account. I have sent another email in May 2015 to have this contract cancelled. They have not done this. I do not want this contract, the staff of MTN seems not to understand this. It does not help calling their help line, no one answers the phone. If someone does answer the phone, they cannot help you and end up putting you through to someone else who also does not answer their phone. I went to an MTN store to have this contract cancelled, they tell me I must call customer services. No one can help me, no one wants to help me. I want this contract cancelled immediately.
