What can i do?

i got my front passenger tire changed today at tire discounters and when they took the old tire off the rubber brake hose came unclamped from the strut and then they put the new tire on without reclamping it.... so every time i turned my wheel rubbed against the line and burnt a whole through it by the end of the day this line cost 30 dollars since they didnt reclamp it and none of this would have happened if they would have are they liable and do they have to pay for the new line
