A Autoworks

I went into a auto works on [redacted] and got an oil change on my car, when they where done with my car the man said everything was good on the car my tire pressure right everything looks good. I paid for the service and left the business upon me leaving I got onto the freeway and my car started smoking and I'm oil light came on so I exited the free way to make a u turn then my engine light came on so as I'm coming up to the light my car just shuts off. I got a ride to the a auto works and told them what happen so we went over to where my car was and the guys pushed it back to the shop. The manager came out and said that they was gone have to keep my car for a couple of hours because when something like this happens he have to contact the owner, so I told I asked him what am I suppose to do about transportation and he said he could get me a ride home but there's nothing he can do. I'm not a mechanic but I no when a car loses all it's oil and shuts down 9 out of 10 the engine is locked up but no one never told me anything. So I'm just sitting at home waiting to hear a response about my vehicle.
