I had a problem with a JA store in Oregon that I visited on vacation. I live in AZ. I emailed corporate, very upset. They emailed me back and forth and finally resolved the problem. Don't stop with the local store. Email corporate and complain - loudly - they will listen and do something.
You just have to find the 800 pound gorilla at the top of the hill who can ajust attitudes and job descriptions. Case in point: I had a problem with the VA supplying a gravestone for my husband. After 9 months of the funeral director trying to get the marker, I told him that I'd take care of it. I called the White House and, after telling the switchboard operator my problem, she gave me the direct phone number for the Secretary of Veteran Affairs. I called him and my problem was taken care of the next day.
