I strongly suggest that you send a replacement for part C, which cracked and fell apart as I carefully removed it from the box.  Yes, perhaps I can drill out the wooden dowels that should NOT have been pre-glued and replace them, but I see no reason I should be required to do so.  It will not be easy, since the tearing and breakage will be difficult to realign.  This is the third purchase I have made through your associated companies, all unsatisfactory for one reason or more.  I have written to the Better Business Bureau about Joss and Main.  I will happily do so about Wayfair.  Would you like that  I write well,  I am well connected via social media, and since retirement, I'm looking for a hobby.  Should it be your products  You can reach me at kmotyverizon.net.  I am currently quite an unhappy camper.
