Worst

Went there to maintain my vehicle through warranty on Tuesday and Wednesday afternoon they handed it back and signed check out papers. On Thursday I saw a leak and returned the vehicle Friday all to find out it's the brake fluid that's leaking then they told me because I came back with a attitude I won't get back my vehicle till the the warranty transaction reflects on their statement so they holding on the vehicle my question i sign any hand over documents and my car is with them my worry if anything happens to my vehicle who will be liable because last time we signed it was hand over to me but the vehicle is with them. I called the head office they said its protocol. I called they store manager they said its because of my attitude
