I understand the communication fatigue, but let's think back over the past years with United.
I (and I think most FT'ers) can remember plenty of incompetent CRS's that have accents that we are more familiar with -- and shop at plenty of stores, etc...
I've had good and bad. Training issues and competent staff are crucial, but if your ear is not tuned for people with different accents, then hanging up and trying again is probably a good move.
It's a tough balance of whether we want an airline that can get back to profits, or one that has higher expenses and FF programs that are in jeopardy. I don't know the best answer.
