No Feedback from the 12/11/2015

Firstly cell phone number *** account is up to date yet the number was blocked due to number ***. On *** I should have been billed only for the Data used in October 2015 and not the device. I had the Samsung S6 only for a month and has been paid in September 2015, the device was handed back to the store on the 01/10/2015. So how can I pay for something that I didn't even have? However I logged a query about this on the 12/11/2015 and received reference number *** from Norma, she said I should receive a call within 48hrs, which I haven't received. I called again on the 17/11/2015 to follow up on my query and Thato told me he will escalate the query to higher management who will call me in an hour that day, which wasn't done. I called again on the 18/11/2015 and spoke to Mosa, who assured me someone should call me within 2hrs. Till today I haven't received a call from CellC to resolve my billing issues. I had problems with CellC from September 2015 and I am seriously not happy with the service I have been getting from CellC, but it's more like no service from CellC And to make it even more clear CellC will not receive a cent from me going forward.
