Airtime and Data gone???

I first noticed AutoPage airtime and data irregularities at month-end when they took the Cell-C airtime and data I loaded a day or two before and gave me my contractual monthly airtime and data. I called on 2 Feb 2016, explained the same issue on both my Cell-C contracts, was given a Ref no: *** and told they'll investigate and to call back the following day. When asked why wouldn't they call me instead, we don't call clients was the reply. I called back 3 Feb 2016 at 15:29, explained, gave my reference was asked to hold the line, and 6:45 minutes later the line was dropped. As a matter of my own investigation I recorded the opening account balance before and after the call. I was disgusted and shocked at the *******. Before the call to Autopage R63.20. After R45.70. an incredible R17.50 for being 6 minutes and 45 seconds on the line to enquire their mistakes, and getting nowhere. And still, Autopage has made no attempt to contact or explain what has happened. Now, how many times have they done this without my knowledge, and surely other clients as well, and stole from us? If this keeps on happening then I'll let Cell-C buy my contract from Autopage.
