Cash Crusaders Athlone Taking my money (False advertising)

Cash Crusaders Athlone is a **** store I bought gravity rush on ps4 on there site via eft on the official site.

Then got the order number and contacted the store to arrange shipping.

Then I get a reply no sorry the game does not exist it was incorrect picture

I demanded a refund and contacted head office and send the store my banking details

Till now there has been no response and no refund

So Cash Crusaders Athlone is okay *****ing my money What kind of branch allows that this is ******* and they treating it as oh its just a small customer problem.
