Pathetic services, **** to! false advertising!

I went to the fourways mall branch on 5 July to find out if I'm eligible for an upgrade. The consultant stated that as of 1 July 2015 I could upgrade. I didn't do the upgrade then and there as there was no stock. On Friday 10 July 2015 I go to Fourways crossing branch. Firstly the one consultant says that there is no stock of the Sony Xperia Z3. I request for him to check if the Cresta branch has stock to which he says yes. A bit later on he says that they do have 3 phones in stock. I told him that I want to take it but he refused to do the upgrade for me and that I must come tomorrow. the one guy walked out of the store and said the other guy will help. He **** and then refused to serve me( the guys name is Mario I think). Angered I go to Cresta to get the phone only to find out that the deal advertised for R 449 was not available on the system. The next day I go back to Fourways crossing only to find out that I'm not eligible for an upgrade. I have been with the networks for a long time and the customer service is revolting. I wasted my time and costs to run around only to be refused a service and **** to. You guys need to train staff to be competent and not lie to people
