Clearly covering up!

I called CellC direct for a new contract, i wanted the G4 which was out of stock, i then requested Note 4....same thing. i then asked Heather to give me some time to think about which device to take. Heather called me back and after a while i then settled on S6 + extra data. I received an sms stating approval . I then called to query delivery date and was informed that its only the sim and there is not stock of S6>>>>>. I then requested that they deal with it and asked how they would solve this issue. I just received a sms saying that i dont meet the criteria??? unsound practice!!!!!!
