Autopage cannot deliver

I upgraded my contract with Autopage assuring me the service was not going to be interrupted due to them closing down, I waited 13 days for the phone to be delivered after they committed 2 to 7 working days. I have 3 contracts with Autopage and the phone of the one contract is problematic and cannot be used. I tried to book in the phone with Autopage in Secunda on 1 March and they said that they cannot book in anymore phones and I then went to MTN and they could not assist me. I phoned Autopage head office on 2 March 2016 and said I need to wait until 1 April 2016 before I can book in the phone. This mean I have to wait 4 weeks plus another 4 to 6 weeks for repairs. This means that I have a contract with Autopage which they cannot assist me. I regret that I decided to do the upgrade and wish I can terminate all contracts with them, their service have been pathetic and when you ask to speak to a manager or supervisor they put you through and you then get cut off. I this the way to treat a customer?
