With no explanation, label text_A→text_B with either "not-entailed" or "entailed".
text_A: I 'm very frustrated at this point - it would take all of 10 min for them to come by and replace the one board that is cracked ( the crack is deep enough to stick a penny in it and it goes clear through ) yet they do not want to take the time to bother with what once WAS a happy customer and has now become a dissatisfied customer .
text_B: The cracking did not happen
not-entailed.
