I had a very positive and productive phone call to AAA complaint center
(the work was done at an AAA Car Care Center). The agent took all my
info, explained that it would be forwarded to the local shop for
resolution. If no resolution, it would go the the GM. If still no
resolution, it would go to the VP.
I contacted the local shop to give the manager a heads up that a
complaint was coming. He was sincerely appreciative that I didn't blind
side him with the issue.
I feel fairly optimistic that the shop will, at least, share the
responsibility for the repair
