Shocking service at Sandton City Telkom

Last week Monday 18 January 2016 I went to Telkom in Sandton City to apply for the Samsung S6 deal. I app**** at 10 am in the morning and was told it would take between 1 and 72 hours to approve my contract and give me a phone. I wasn't contacted on the Monday again so I went in on Tuesday. I was told my contract was approved but they didn't have any phones and they will receive them on Thursday. So I went in on Thursday and there was still no phones! I asked when will they receive stock and I was told they don't know. It has now been a full week and I still have not yet received my phone and no call from the shop to date. Another gripe is the shop's telephone number does not correspond to the website details. If this is not resolved I will cancel the contract as I have not received delivery of my phone and I will go to the competition.
