Phone Order

I've ordered a phone, a Sony Z3 with Vodashop Cresta on the 2nd of May 2015, and I haven't received it till today (19-May-2015). I've been trying to survive without a phone till today, but I can't no more because this is affecting my work as well. Whenever I call them to find out if my phone is ready for collection they tell me that the phone is on backorder and they promise to reorder. No one cares to update me on the status of my order, I always have to be the one calling them. Isn't Vodacom's responsibility to follow up with their supplier to make sure that they get stock in time.<br> <br> When I ask to speak to the manager, they deny me the opportunity, telling me that he's going to tell me the same thing \Back Order". I have asked them to check if other branches might have the phone that I am looking for"
