I thought that those tickets were related to EK sponsored events, and therefore there would always be a EK counter ...
I'm also surprised that OP didn't receive a detailed e-mail indicating how to retrieve the tickets, or even a mail with the e-tickets themselves.

I feel sorry for OP. I hope that EK will show understanding ...
