When pressing some of the dowels in, they went straight thru the pressboard and out the side of the cabinet.  Happened in two of the six dowel locations on the first piece I was putting together.  Submitted a return request web form three days ago and have not had a response from customer service.  Followed up with a direct email to service yesterday and have not heard back.  This is our first purchase from Wayfair and not impressed thus far.
