I'd follow it up as much as you can.
I remember we had a similar problem a few years back. The fuel pump died. We got a replacement fitted. Mechanic didn't fit it properly so the car broke down again the day after we got it.
They tried to bill us again after having fixed it, to which they got a phone call and basically told where to put said invoice.
On the bright side, you still have your health, money and material possetions are nice, but they can't fix everything. Good health, good company. Free and worth so much more than money can give
