i had a similar problem, i went to my shop to get a wheel straightened (it wasn't a bad bend, just enough to kiss the brake). So i call up the next day after they said it would be done before closing the day before. they tell me " yeah, we actually cant find your rim, were gonna need to get back to you on that one" they eventually found it after two days of looking in a extremely small shop, and straightened it for me and sounded like he just threw it together, the next day i was on a relaxed ride, when i was making a slight left at 16mph (no bumps, cracks in the road) when all of a sudden the rim just bent to the right hand side and i ended up walking 10miles home. I didnt bother taking it back because all the guys there are a**h****. I learned to do it myself, and swore never to go back.

i would say check out the rims see if its okay to ride, and than just try to shop around to different shops if your not happy with the quality. Or learn to lace wheels yourself.
