Dubai-based Spencer Lodge pledged the cash, to be used for a day out with the legendary singer and husband David Furnish, at a ball.
But despite singing a contract promising to pay the money to the Elton John Aids Foundation, the charity is yet to receive any money form the banker and has started a High Court (pictured) action in a bid to recover the cash.
Sources quoted by the Mirror said the couple are “really angry”.
The day out included a trip with the couple to visit some of their charitable projects in the UK.
Lodge is well-known on the Middle-Eastern business and celebrity circuit, added the paper.
