Query: Poor quality all around

Unfortunately I spent an hour assebmling before realizing how poor quality it was. The caster mounts are all bent to different angles so it wobbles a good 1/2" or more. I'm afraid to bend it as that will weaken it. The bolts are such poor quality the heads are not standard sizes and you have to go at it with several wrenches because you don't know what will work for each bolt. There was a good bit of rust on mine out of the box. ALso, one of the rotating casters hits a bolt so it will not turn all the way around. I'm trying to get this returned as fast as possible and will most likely make my own base. Sigh...
