A pretty annoying story, and clearly a tribute the outsourcing-heavy state of this industry. Not sure how I would have acted. Probably I would have been confused just like OP. Good we have FT. Just remembered a trick: remember a taxi or rental as a way out of trouble.

I also have learned many times that a working mobile when flying simplifies problems a lot. This is not an excuse for SK but a lesson for you (in the times when one cannot rely on the service in outstations a working mobile is key). I recall an LO cancellation out of YYZ when I had no working mobile. I was given a local number to call, and had to literally beg people for pennies, as the airline judged that I should be able to make a local call from a pay phone. Of course had no cash on me either.
