balk and offensive interference

[_Bruno_]

R3, 0 outs.
balk followed by a wild pitch. R3 tries to score but the batter interferes with the catchers throw to homeplate (to the pitcher).
whats the proper ruling ? TIME, enforce the balk ? or any penalization to the batter (batter out, R3 scores) ?

same sit but we had a R2 and he would try to score on the wild pitch, and the batter interferes, call the batter out and send R2 back to 3rdbase ?

what i exactly wanna know is, is there a situation, in which the balk is disregarded and the offense penalized, even if a runner did not reached his advance base or a batter runner did not reach first base ?
