What should i do with this retarded game>...>?

i bought dbz raging blast 2 for 60 bucks..the game is just plain retarded... online sucks because your opponent will not let you do anything, if he gets 1st attack your f0cked you just gotta sit their until he decides to stop making ridiculous combos which you cant cancel..if you try to hit your enemy and if he moves just a bit to the side and you both try to hit each other both persons hit nothing.the camera is also lame if the enemy is just ontop of you and you try to hit him geuss what your just swinging punches... and the characters mover really slow even in super dash they move slow.... i tried returning the game but they said no i could only get 20gamestop store credit. also if you try to do a combo in that game halfway in the combo your gonna be laying on your back in the floor saying WTF just happened. should i burn this game beacuse thats what i do to games that i dont like(CoD).
