sounds like there trying to make her fork out more money for their f-ups.. something similar happenend to my mothers car . she went for a radiator flush and they busted her radiator... it leeked all the fluid out and he was running on nothing for who knows how long... best they did was give her a new radiator and she had to fork out $250 for parts alone... no labor charges i persoanlly would look into ways to sue these a-hol3z .
