Boxing fans in America were left fuming after they were unable to watch the Floyd Mayweather vs Logan Paul undercard fights.
Asked to spend just under $50 for the privilege, fans across the Atlantic then found they could not stream the opening bout between Chad Johnson and Brian Maxwell.
Showtime, who were showing the fights in the US, apologised and assured fans they were working to resolve the issue.
But that wasn’t enough for some who demanded a refund.
“We all paid and we have receipts, give us at least a partial refund,” said one on Twitter.
Another added: “I’m having an issue. Show is already on too. We deserve something for this.”
Showtime tweeted in response: “If you are having issues watching the fight on showtime.com or on the SHOWTIME app, please try again in 10 minutes. We are working to resolve the issue.”
UK fight fans seemed unaffected by the technical issues with Sky Sports showing the fight on their Box Office service.
Mayweather and Paul will later clash over eight rounds in their exhibition bout which will have no official winner.
Both men have promised to stop the other – which is allowed within the rules.
But Paul will have to bridge huge gulf in class having fought just once as a ‘professional’, losing to social media rival KSI in 2019.
Mayweather, meanwhile, was one of the greatest boxers of his – and any – generation during his glittering career.
He won all 50 of his professional bouts with his swansong coming four years ago when he stopped UFC legend Conor McGregor in the 10th round.
He subsequently stopped Japanese kickboxer Tenshin Nasakawa in the first round of their exhibition bout in 2018.
And Mayweather dismissed suggestions he will be at a disadvantage due to Paul’s height and weight after the YouTube star scaled 35lb than his opponent.
“I’ve been here before, so I know what it takes,” he said. “I’ve fought every different style you can possibly fight.
“Height don’t win fights, weight don’t win fights, fighting wins fights at the end of the day and I can fight.
“Once again, I’m not worried about a hat. I don’t worry about what nobody says. The one thing I can do, I can fight. I’ve been at the top level for 25 years, so I know what it takes when it’s a fight of this magnitude.”
