As part of a sweepstakes prize, i was given a 7 day sixt car rental. I tried calling the number given to make my reservation but was unsuccessful because none of the #'s i gave to the agent were correct? or she couldn't find any of them. the worse thing is i don't speak or understand a word of german, and while the agent had pretty good english, there was a slight language barrier.

anyone have experience using one of these that could help?

The only #'s i see are the order number, agency #, and KST. The agent kept asking for the voucher # which i can't seem to find or im just really blind!

any suggestions?
