whether they tried to call you and if they have always had that policy is irrelevent. If they are gonna have a blanket policy against all preorders they should display it in writing in the shop and give it to you in writing on the receipt or something.
They more than likely hide this point away thus only telling people verbally so it doesn't act as a deterrent when getting the business from you and leaving them to hide behind these pathetic "we did try to call you" lines. Bad customer service IMO as they have annoyed the shopper who trusted Gamestop when planning in advance and may have been more loyal in the future than a random person walking in and buying it off the cuff.
In terms of annoying and losing your potential loyal customerbase for instinvtive fad shoppers - Gamestop just pulled a Ubisoft.
