I can assure you it is true Rangerz.
The odds would have been no different for this bet if the score was 2-1 or 0-0 (well slightly different but the current score is not very relevant to the odds)
The problem was simply a bet listing error. They told players the current score was 0-0 when it was 2-1. It really sucks for the OP who sounds very much like he bet in good faith to lose out on a technical error. But with that odds movement it appears the bulk of money went on the logical side to take a shot, and Liverpool backers would have complained.
