I bought NHL 3on3 Arcade from the Playstation Store, and had to send in my Playstation 3 to Sony to have it repaired, but when i got it back, the game was gone, is there any way I can get it back?

alright so i found out that my ps3 disc drive is all fucked up so i called sony their like o ur warranty is up u will have to pay 150 freaking bucks, ive going had it for about 2 years its BS and im not pay 0 to replace it unless they up grade it, idc what they say if it gets lost in the mail some how they will just make something up and say it was my falt, so i was just wondering if game stop would fix it for me or some other game store
