Since that Insta post on Thursday, Newsbeat's spoken to others who haven't received their fees from Manchester Pride - which is a registered charity.
Mathu, who performs DJ sets as Choke On My Pronouns, was booked to perform a set at Depot Mayfield, a large capacity venue, on 23 August.
They tell Newsbeat they were told to expect payment by 5 September, but when that date passed they chased up the organisers.
According to Mathu, they received "generic" responses that said the event was experiencing delays with payment.
Mathu thinks headliners will be hit less hard than some of those lower down the bill.
"It's not really affecting them that much if they don't get paid because they'll be getting money from other gigs, other shows, the fans and that kind of thing," they say.
"So I think it affects us a lot more as smaller queer artists because we rely on this money to pay our bills."
