The “Say So” singer changed her name before the new Twitter Blue subscription came into force.
The original verification system was intended to identify real influential people, including government figures, sports stars, entertainment figures, journalists and major brands and organisations.
But in the controversial decision, Twitter has allowed anyone who pays for the service to have a tick.
In the aftermath of the new rules, it appears Doja is now stuck with the name and cannot change it back.
"Why can’t I change my name on here," Doja tweeted on Thursday (10 November).
"How do I change it, also f*** you Elon,” she said in a series of posts.
"I don’t wanna be Christmas forever [Elon Musk] please help, I’ve made a mistake," she wrote.

“i don’t wanna be christmas forever @elonmusk please help i’ve made a mistake,” the artist added.
Musk responded to her tweet saying: “Working on it!” before replying with another comment saying “Pretty funny though” with crying laughing emojis.

Doja also tweeted two voice recordings in which she said: "You guys are paying $8 a month to come on here and go to war with people who are not in agreement with who your favourite pop star is."
"You’re paying $8 a month to come on here and say [stuff] like ‘bye’,”she said.
"Umm you’re coming on here for $8 a month to post porn and then get into an argument. I think I can stop there. Ok, cool. Bye,” the star added in her series of tweets.
