Donors to Prince Harry’s pet charity project are reportedly fuming over he and wife Meghan Markle’s decision to take a step back from palace life in London.

Supporters of the Duke’s Invictus Games Foundation — which he started in 2014 to benefit wounded soldiers returning from the war in Afghanistan — reportedly said he left them feeling abandoned when he moved to Canada earlier this year.

“I am just bloody angry,” one supporter who has given thousands to the charity told the Sunday Times of London. “There is this expectation that we go out and flog ourselves and find support bringing in cash for Invictus. He could make this a whole lot easier if he did something as well. He could text anyone.”

Another volunteer claimed he made his Megxit without thanking Invictus supporters or reassuring them that he was committed to the charity.

“Everybody has been unwavering until now, but everybody feels they have been dropped like a bad habit,” the second volunteer said.

Harry and Meghan announced on Jan. 8 they would take a step back from daily royal duties and raise their young son Archie in North America.

In a move that highlighted the severity of the family feud inside Buckingham Palace, the Queen yanked “royal” from their title last week.

Despite backlash from volunteers, charity bosses are publicly supporting Harry.

“We are proud to have the Duke of Sussex as our patron. The Invictus Games was founded by him, has been built on his ideas and he remains committed to the games and the foundation,” CEO Dominic Reid said.

Harry is scheduled to return to London next week when rocker Jon Bon Jovi re-records his hit single “Unbroken” at Abbey Road studios in an effort to raise $2.6 million for the charity.

He and Markle are both expected to appear at the Invictus Games in The Hague in May.
