Contract not upgraded as agreed

I upgraded with Autopage in Dec 2014. I clearly indicatedthat the contract st be a top up account. I called on numerious occations and hld on for long periods before somebody answers. And ten we pay for the call. I called again on 9 March after my account was billed with nearly R800. I spoke to Maybel Komane and she promise that Michael will call me and we will vlarify the contract as agreed in December. Todat is the 8th and no responce. Drom Autopage. I still don't know if my contract is now a top up account. The minutes and smses and mb data is now correct. But I can't get through to Autopage because a voice message tells the whole time all the consultants are busy. I have been with Autopage for 13 + years and am very unhappy with the way I am being treated by the company. And I was promised that they will get back to me asap an will refund me as soon as they have sorted out the query. And still no response from the company.
