His suspension came hours after he used abusive and homophobic language to target journalists, including a gay CNN presenter, Don Lemon.
Twitter has not commented or confirmed if Stone’s suspension is permanent.
Since then, Mr Trump has tried to put some distance between himself and Mr Stone, who regularly appears on network television to support his former employer.
In a Facebook post, Mr Stone said he believed his suspension should have ended “some time ago yet my Twitter feed is still not functional”.
He added: “Several media outlets are reporting that I have been permanently banned but Twitter has not informed me that that is the case.”
One of the people he targeted on Saturday, CNN contributor Ana Navarro, said she did not sympathise with Mr Stone over his suspension.
