Disapointed

I am not normally someone who does these things but I honestly don't know what else to do. I took out a contact about two weeks ago for a Sony XA1 and a Ps 4. We went through the whole process, the contract was approved and we paid the connection fee and everything , just to find that Festival mall Vodacom gave me the wrong phone and they needed to take my sim and everything else out because it was not the XA1 they gave me but the Z1 or something like that, then only did they tell me that they didn't have stock. They gave us the ps4 and told us that we would get the phone in a few days. its been +- 2 weeks and still they cant tell me when they are getting the phone. now I want to take the other phone L1 that comes with the ps4(because I already have the ps4) and they tell me that cant be done either. so please tell me what I am suppose to do as I am paying this now for the second time but still don't have a phone???
