A football fan who thought he'd scooped £15,000 after placing a £10 bet on the World Cup claims Coral won't pay out.
Punter Liam Manifold correctly guessed Argentina would win the tournament, Lionel Messi would be named the player of the tournament, and that France would make the final.
The 30-year-old put down £10 on a treble at a Coral shop on November 11, giving him odds of 1,495 to one.
Liam said he had already decided how to spend his winnings after his predictions came true and raced to the bookies - only to be told it wouldn't be paying out it.
The maintenance engineer from Tutbury, Staffordshire., planned to buy his dad a new mobility scooter and save the rest.
Instead, Coral said the bet was placed on events that were too "closely related" and couldn't be included under the same accumulator, despite Liam claiming the staff member who took the bet said it was fine at the time.
"I went to cash in the bet and they said it shouldn't have been placed and offered me £660 for it," he said.
"I've gone through their complaints system, there's no leeway. I've gone to an independent complaints committee and I'm waiting to hear back from them.
"I've since had different companies contact me saying if that was their company, they'd pay out. When I placed the bet the guy behind the counter said it was absolutely fine. They're now saying it's a related bet.
"It's now two weeks after the final and I don't seem to be getting anywhere.
"If there's an error it's their fault for accepting the bet. It's very frustrating.
"Just under £15,000 for a big betting company is pennies for them, but for me it's a life-changing amount of money. My dad's disabled so I was going to buy him a new disability scooter and keep the rest in savings."
A spokesman for Coral said: "These three events are all closely related to each other so the prices that were offered on them individually can't be included in a multiple bet.
"If Argentina and France have made the final, then the odds of Argentina winning it are clearly much shorter than they were at the outset.
"If Argentina have then won the World Cup, the chances of Messi being player of the tournament will be long odds-on."
Coral instead has settled a sum, which Liam said was £660.
The spokesman added: "So we have settled the bet in the fairest way possible, paying out on the event with the biggest price, an Argentina v France final, at 22/1, and then on the basis that that had happened, we applied the price of Argentina winning the final which was 10/11 before the game, and then on the basis that Argentina had won the cup, we applied an over-generous price on Messi to be player of the tournament at 1/2, as the odds on that happening should Argentina have won the World Cup would have been much shorter.
"The prices on the slip had been written on by the customer not the member of staff.
"We have settled the bet in line with our terms and conditions, and we have made a very fair and generous offer for the settlement of the bet that exceeds what would have been the odds of such an eventuality had a customer asked for rush specific treble on November 11."
