I paid £287.46 for a ticket to see Stevie Wonder and Aretha Franklin in concert on the Viagogo website. Later, when checking the website of the concert venue, I discovered that it was a tribute performance by other artists.

There is no mention of this on Viagogo, whereas other websites, like Live Nation and Ticketmaster, make this clear.

AA, London

The official title of the concert is Signed, Sealed, Delivered – the Music of Stevie and Aretha.

Only Viagogo omits those crucial three words “the music of” and you are unlikely to be the only customer who was misled. Viagogo declined to comment but has issued you with a refund after the Observer pointed out the misrepresention.

Always check the details – and ticket prices – of a show with the venue before doing business with agents that sell on pre-sold tickets.
