Hootie

I had remote installed today on a MT. The guy told me never to put it in gear when I turn the car off. I picked it up, stopped for gas, went to get in the car and I had my keys in my hand and must have activated the remote start. I had the emergency brake pulled. The car took off, dragging me with it. It went over 3 curbs, bushes and finally came to a stop. They never gave me an instruction manual........is this because they had to disconnect a safety feature on the car? I had it done at the dealer and it was part of a package deal they offered me. The car is messed up and I know it can be fixed. It's just that I know that it has been damaged. Can anyone tell me about these remote starters? I have never had one before. Should I contact an attorney? If they did disconnect a safety feature, no one told me about it. Please help.
