They left a voicemail, they were not asked. It said "Thanks" and then "But..." and then a whiny recitation of the complaints.
There is more to the story, but I wanted to see if I was out of line to even intially react badly to this "thank you."
The tix were through my job and were picked up by my uncle at the will-call table. He was erroneously given the wrong tickets. He should have been in the 7th row, instead he ended up in an upper tier in the back. But he knew his seat assignment because he was sent an email with all the details. Instead of questioning the staffer who gave the wrong tix by accident, he and his wife sat in the "bad" seats.
After the "thank you" I checked with my coworker who worked will call. She explained what happened and figured out how she screwed up and gave him the tix in error. It was fixable but my uncle and his wife played the martyrs and never spoke up. I emailed uncle to tell him it was an error and my colleague was very sorry for the mixup! Uncle then replied back and insinuated that she probably took his tix and gave them to a friend or family member of her own.
This second comment by him has put me over the edge.
