Poor Customer Service

So on the 17th I went to complain about my line still being suspended since May ref ***. I was advised the reason for this is due to credit which was the 3rd incorrect reason. Anyway was then told it was due to an error on my line. I then went in today after being told 72 hrs. 23/6/15. Today I was advised I need to first make a payment for them to help me as my current payment was due yesterday. After making a double payment and a missing payment paid into their Absa account. Agent advised me she is frustrated and I am holding up the queue after I stood there longer than 30min waiting. The manager advised my account is hard locked and she sent a request now and sent off my proof of payment. Pop now sent x3 to Jhb. Line off now since beginning May. During this entire ordeal I have never been contacted by Mtn I had given them an alternative number. I have been doing all the run around and today the agent asked me what do u want me to do? I said track my missing payment that I paid into your bank details supp**** by you. Where my other payments was received no problem. With the double payment taken under duress as I needed to be contactable. I should be in credit with the 3 paymen
