When I had a problem (my air reservation for the next day appeared to have been cancelled), I learned I couldn't communicate with them via email. I wasn't carrying a phone. My hotel in Bari, Italy didn't have a phone they would let me use.
I had to find one of those phone places to make a call. The first one wasn't able to help me figure out how to get through. The second one realized there was a button on the big wall phone that had to be punched for overseas calls. Minimal English in the places, and my Italian is pretty much confined to manners words and food words.
It did get sorted out eventually. They said it was some "computer glitch".
I had bought other tickets from them previously with no problems though.
