Billed on an undelivered phone

In March 2015 I took out a contract with Chatz Conect throught the Roodepoort Westgate branch. I was informed by Graeme that the phone would have to be orderd as it was out of stock and that it would be delivered to me within 2 working days. 3 working days passed without any delivery. When I inquired with Graeme, he said the delivery person would come the following day. No delivery took place the following day and Graeme failed to update me. 2 days later I called Graeme who said that the delivery guy was on his way to deliver my phone and that I should expect it after 12:00. No delivery occured.. I then went to the shop a week later to find out exactly what was happening. Graeme said: \Your phone is at our Horizon View branch as we speak
