Wow! I'm sorry to hear about your experience. Hearing this makes me so mad because I have been living and seeing similar issues on AS this year. To make matters worse, their customer service in resolving or compensating for these bad experiences has gone to hell too. I recently posted about my experience as a 75k being bumped on the standby list and then being offered a seat that had vomit on it... I wrote a letter to AS and received a response 3 weeks later that basically said, "sorry boarding procedures weren't followed.." They didn't even address the disrespect I received in being offered a seat that no one would sit in because it wasn't sanitized! No miles or compensation offered. I just wanted an apology and acknowledgement that they screwed up and I didn't get it!
If you are going to complain, I would recommend tracking down someone higher up the food chain than customer service, maybe a VP or CEO. If they don't listen, give your business to Delta!
