Bests & Worsts Reviews from Amazon

I bought this bed for my daughter. I put the bed together, and it was going along fine until I was attaching the last rail (c) and I noticed that there were no threads in the hole. When i tried to insert the screw and install it, it just fell out. That did not happen with all the other rails. they all worked fine. the part was basically defective as there are no threads. So I called Zinus and I got an email from them after our talk. They were going to send me slats instead of the rail. So I called back and said, I don't need the slats, I need the rail C to be replaced. The man I spoke to said ok, they would expedite the request. About 15 minutes later I received an email that they will not be sending the rail, and I will have to deal with Amazon to send the whole bed back. I was like....REALLY? I need ONE part from you! I purchased this on October 22 so any warranty would still be good, right? I guess not. I am really disappointed with the Manufacturer on this one. All I needed was a part and they said NO.
