Dozens of Taylor Swift fans, and one angry lawyer/Swiftee, want Ticketmaster to stand trial for allegedly screwing them outta tickets ... and right now at least, they're not interested in settling.
Attorney Jennifer Kinder filed the lawsuit last week against Ticketmaster, and she joined us Tuesday on "TMZ Live," and explained why she's not buying the company's claim that the presale event problems were simply a supply and demand issue.
Jennifer says it really comes down to simple math, and it should have been clear to Ticketmaster things were gonna go south when it gave out way more presale codes than there were seats available for Taylor's 'Eras' tour dates.
TMZ broke the story ... the fans are alleging Ticketmaster essentially got into bed with scalpers by allowing bots to block real fans from getting tickets -- and the reason comes down to money. They claim Ticketmaster benefits financially when scalpers resell tickets.
