Did you re-install the QR-skewer to hold the freewheel-remover on before trying to wrench it off? Manually screw in the QR nut until it's tight over the freewheel-remover, then unscrew it by about 1/2 a turn to give the tool and freewheel room to back out. After you break the freewheel free, unscrew the QR nut some more and unscrew the freewheel.
Even if the notches are buggered, it's still possible to remove the freewheel if you keep the QR tight on the tool. If the prongs on removal tool are broken, get another one.
