We were approaching less than 2 mile short final to land; when Aircraft Y called base to final; in front of our aircraft; cutting us off; as we were verified by other pilots in the pattern that we were #1. Even after 5 initial traffic calls issued by us; announcing base and final 3 times; she dismissed our traffic calls and cut us [off].Upon us telling her to go around and that she was at fault; she refused again and again and prompted us to go around to avoid a near air collision.
Aircraft Y was on the downwind leg; we were on a 2 mile final and they cut in front of us.  We had reported our position more than 5 times on the base and final leg portions of the approach. The other aircraft just reported turning final.  We requested she break off her approach due to the conflict but she refused. Due to the proximity we had to break off our approach.
Pilots reported NMAC on final.
