Last week’s Champions League game between Chelsea and Paris St. Germain was exciting for so many reasons but not for Sky Bet’s furious customers who cried foul when the online bookmaker failed to honor odds after PSG’s dramatic comeback to secure a place in the quarterfinals.

According to the Daily Mail, some customers were furious upon learning that Sky Bet dropped the odds of PSG winning in extra time to 9/2 after initially the bookmaker’s mobile phone app initially posted a line of 25/1. What that means is an initial bet of $1 would have paid out $25, not $4.50 on the revised odds.

Sky Bet Managing Director Richard Flint admitted that the 25/1 odds were posted incorrectly and that the company argued that its decision to drop the number when it came to paying out winning bettors was keeping in line with its terms and conditions, which explicitly says that the company reserves the right to “correct obvious errors and eaters settle bets at the correct odds or void bets.”

“Occasionally mistakes happen,” Flint added. “In this case a wrong price was displayed for around three minutes, and a small number of customers bet at the incorrect odds. These odds were clearly wrong – we showed odds of 25-1 when the true odds and the odds displayed by all other bookmakers was 9-2. We settled at the correct odds.”
