Query: Missing Parts

I have ordered this playpen 2 times and both deliveries came with missing parts. There were absolutely no instructions or hardware to assemble the pen door. I attempted to call the manufacturer to obtain the necessary hardware but was never able to reach a person. I left 2 voicemails and have yet to receive a return call. I then returned the item to Amazon and a replacement was sent very quickly. The problem was the 2nd delivery arrived the very same way - no hardware! Amazon is quality checking the items now. I do like the playpen but am very disappointed with the lack of customer service from the manufacturer. Hopefully I'll be able to receive the item with all necessary parts to assemble it.
