ps3 freeze dragon age inquistion

PS3 After playing for over seventy hour I cannot load any of my games. I can get to the loading screen- continue freezes on load- load save game freezes on load. The game froze frequently but I was able to reload and start from a save game. Frankly I'm disgusted that a game can be released with so many bugs. I've invested a lot of time and money on this game. I will avoid other ea games in future. I'm totally disappointed. If the PS3 hardware can't cope why release it on PS3?
