Bis billing recorded incorrectly.

on the 3rd of June 2015. I spoke to a cell c call centre agent to help me load BIS on my phone, not knowing that the latest blackberry's (z3,z10 etc.) have their own blackberry bis plan, the agent loaded the incorrect bis for me, the next day my phone started giving me problems, my network went off and couldn't access my applications, on Friday 5 June 2015.i called to inquire about the problem and I spoke to another call centre agent working in the technical side, and he told me that the wrong bis was loaded in my therefore causing my phone to have problems, he then suggested in opening a case for me to resolve the matter and that I would be contacted in 24/48hr working days by cell to resolve the issue, on the 7th June I still didn't receive any feedback regarding the matter, and I had to call cell c again to ask what was happening and a female call centre agent just said the case was dismissed because the customer did not specify what kind of phone she was using, i lost my airtime and the data and di not even get a call to apologise for the mistake, instead I was told that \I"as the customer was wrong. strongly considering changing networks! UNHAPPY! """
