Me and CellC again. . .

So after I gave up on my wireless charger that was promised and never received I'm now sitting with a bill query. . . Being charged for a 3GB that I did not ask for nor received. On the tax invoice is that the 3GB is 100% discounted but charged for. After I've phoned last week and was told someone will contact me withing 2 business days that did not happen and after another call to CellC yesterday the 19th of Jan someone was supposed to call me yesterday the 19th and that did not happen I still sit with the problem that it would be deducted from my account within a few days. The amount will be deducted from my accout in a few days and on this rate I will not get it resolved before the end of the month.
