Chevrolet service near West Columbia, SC

They didn't put parking brake on or leave car in gear (it is manual) so it rolled and collided with another vehicle. They made appointment to REPLACE the bumper and said they would have rental for me to drive that day. I showed up to find a junk Chevy Volt that has Midas plastered all over it and stinks like cigarette smoke waiting for me. I refused to drive it so instead of getting me a rental the tech offered to drive me home and pick me up or drive our car home when it was fixed. Well I'm sorry, even if I wanted to get in a car with a strange man and also let Midas drive the car they just wrecked, I live 40 minutes away, so no. They should have arranged a rental. Also, they said they were replacing the bumper but now they are going to try to just fix it even though it has cuts in it (not just dented).
