Complaint Review: Zombie Bikes

I went to Zombie Bikes on September 29th and looked around at their bikes. They have a small shop at 6130 Montana Suite 212 (on the top level) (they have no website or Facebook and their phone was disconnected). I went ahead and purchased a bike from them as a gift for a friend of mine. The very first time I sat on the bike, the back part of the bike frame cracked loose and broke.

Come to find out they had re-painted the bike over heavy rust and the metal was very brittle. I went back to the shop to return the bike and they refused. They staff is VERY RUDE, and the second time I went to their shop the place smelled so bad that I almost threw up. There were three guys working there and none were helpful. They said they would not retire
