Pin was seized inside shoe - Tyrant CNC I.T.T.S Glock Hybrid Pistol Triggers

I have the proper block and punch and have performed this job countless times on all manner of Glock aftermarket trigger shoes. I have never had a pin seized inside the shoe to the point where I could not get it out. I was so patient with the stubborn pin and was able to move it about 1/2 millimeter. In frustration and after 30 minutes of trying to do something which should take 1 minute— I then took a heavy hammer to the pin and STILL it would not budge. I even said “screw it” and went full force on it. No movement! I then went after it like a crazed animal and marred it up…. Still no movement. And now it has visible flaws which means I can’t replace/ return it. I’m puzzled and upset.
