Cell C does not communicate with customers!

I app**** as a new customer with Cell C on the 29th of January 2015. I had to phone them again on the 2nd of Feb because no one had told me if the application was successful...only to find out that there was a problem with viewing my payslip but no one had had the decency to let me know. Then i was told that I would get my phone within 3 working days, these went past with no response so I then called in, only to be told that it would be delivered that same day or the next day. This did not happen.On Friday the 6th Feb I sent an email to enquire only to receive an sms saying that they were out of stock....Why could they not have told me about this from the get go?I have cancelled the deal with them and am still waiting for confirmation of this too.I am truly disgusted, if I treaded my customers like this, I would be fired!They keep promising things that they cannot deliver. No one has even apologised.
