No Xfinity Store at appointment location - "Jefferson Square - Seattle"

When I received my appointment confirmation today, the automated system said I had an appointment at "Seattle, WA - Jefferson Square".   Unfortunately, there is no Xfinity Store at Jefferson Square.

The Xfinity Store is located at "Seattle, WA - Westwood Village".

I did find the right store eventually, and then got a message after my appointment ended that said that my "Xfinity appointment at Seattle, WA - Jefferson Square...has been canceled, either based on a recent request you submitted or due to an unexpected change in store hours."

The Xfinity store representative that I spoke to said that he receives NUMEROUS complaints about that, with people missing appointments because they were sent to the wrong location.   He also said that he put in NUMEROUS requests to corporate headquarters to get this problem fixed.    This problem still persists.
