When I opened the box with the storage bin enclosed I found that two corners of the bottom section were bent.   Straightened the corners but the coating fell off.   Also, when checking for components necessary to assemble found that screw BF were attached, but according to assembly diagram I should have had BB screws.  Contacted service representative that determined I should have BB not BF.   Sending out BB screws, now waiting four days and still have not arrived.
