The lawsuit, accusing CoSport of breach of contract and fraud, was filed in April by Susan Caruso, an "avid supporter of the U.S. Olympic Team".

According to the complaint, Caruso spent $16,375 (£11,734/€13,787) to purchase CoSport’s Tokyo 2020 Olympic Games SS Package, which included tickets to multiple sporting events and a five-night hotel stay.

Another plaintiff, Susanne Galanek, parted with more than $10,000 (£7,200/€8,500) for a package including hotels, hospitality and tickets to multiple events at the Games.

"We were planning a trip of a lifetime, so we were really looking forward to it," Galanek said, as reported by CBS Philly.

"We were going to go to diving, volleyball, swimming and we had tickets to go see the semi-finals of basketball."

As coronavirus cases began to surge, prompting organisers to ban overseas spectators from the event, Galanek was only offered a 75 per cent refund as CoSport would not give back the handling and service fees.

Galanek is represented by law firm Kimmel & Silverman, which alleges that CoSport violated the New Jersey Consumer Fraud Act.

"From the contract that I read there was no intention on either parties part to have a charge in the event of something like COVID," Craig Kimmel said, per CBS Philly.

"You look at the terms and if the terms don’t say CoSport can keep the money, they can’t keep the money."

The New Jersey-based company claimed that it had already provided more than $23 million (£16.5 million/€19.5 million) of cash refunds for Tokyo-related tickets and hospitality expenditures and that it planned to provide $9 million (£6.5 million/€7.5 million) more "in the coming weeks and months", it wrote in its motion to dismiss.

CoSport insists that customers were told of the refunds they would be entitled to in the event of a cancellation, and that the plaintiffs all agreed to those terms.

According to the accusers, CoSport deceived them over the nature of the refund process.

CoSport, meanwhile, says that it is being subject to a "shakedown" based on a "malicious accusation" that it has profited from the course of events.

"CoSport did not make an untold windfall on the Olympic Games," the company wrote to dismiss the claims.

"Rather, absent any legal obligation to do so, CoSport reached into its own pocket and guaranteed its customers refunds they were otherwise unlikely to receive.

"Plaintiffs call that unlawful conduct and fraud.

"It is not."

CoSport is also an ATR for Sweden, Norway, Greece, Bulgaria, Croatia, Jordan, and Australia.

It is estimated that $800 million (£575 million/€675 million) worth of tickets for the Tokyo 2020 Olympics went to waste, with domestic fans also banned from the majority of venues.
