All's well that ends well.  

I had engaged Handy to assemble the 6 office chairs we'd bought to use as dining chairs.  I paid for Handy to assemble them because I didn't want to blow the better part of a day putting them together.  It takes a god half hour to assemble an office chair.

The first guy who showed up to assemble the chairs, well, it is possible he'd never assembled an office chair before.  He did a sloppy job.  It needed to be redone.

Wayfair and Handy were all about the service.  They were mortified that the job hadn't been done right in the first place and sent the replacement parts necessary and were very proactive about scheduling someone to come out and finish the job correctly.

The second guy did a great job.  

The point of this is that despite an initial error, the job was corrected as soon as humanly possible.  Employees sometimes make errors.  Wayfair and Handy were intent upon me being satisfied with the service and made that happen  That's professional
