LONDON •Adele fans affected by the British singer's last-minute concert cancellations have taken to social media to vent their fury.

The Grammy-winning star, one of the world's best-selling singers, posted on social media last Friday that her two sell-out shows at London's Wembley Stadium last weekend would be cancelled.

The 29-year-old had damaged her vocal cords and said her throat doctor had advised her not to perform.

While ticket-buyers are set to get refunds, many have questioned if they would be reimbursed for travel, hotel and other costs. Many had travelled to London to attend the shows, The Daily Mail Online reported on Sunday. About 100,000 people were expected over the two nights.

One fan, Facebook user Tash Carr, wrote on the platform that she felt "cheated" and said the singer's decision to add extra dates to her current tour due to high demand had led to her strained voice.

Another who calls himself Ian J. Fudge wrote: "My friends who were flying down from Glasgow are pretty disappointed - lost a fortune in flights and hotel."

Fellow social-media user, Mr Andrew G. Dick, criticised the star's "zero work ethic". He added: "Many artists perform well into their 60s/70s whilst wouldn't dream of letting their fans down."

Meanwhile, The Sun reported that Adele stood to lose millions of pounds in earnings as footage from the cancelled concerts would have been used in a planned DVD release.

The Daily Mail also reported that terminally ill grandmother Lisa Middleton, 49, was crushed when her favourite signer cancelled the gigs.

Told that she has only a few months to live, she fears she might never get a chance to see Adele live as the singer has mentioned giving up live performances.

In a handwritten note included in last Thursday's concert programme at Wembley, part of a 123-date global tour, Adele hinted she might retire from touring.

"Touring is a peculiar thing. It doesn't suit me particularly well," read the note, which several fans posted on social media.

"I'm a real homebody and I get so much joy in the small things. Plus I'm dramatic and have a terrible history of touring," she wrote. "I wanted my final shows to be in London because I don't know if I'll ever tour again and so I want my last time to be at home."
