Car is dead in a parking garage

It’s very cold where I’m at. I parked my car in the parking garage for my work and when I came out to go home it wouldn’t start.

Multiple people have tried to jump it and nothing is working. No tow trucks will come out to tow it because of the low clearance of the garage (8 feet).

So my car won’t start, can’t be jumped, and can’t be towed. What do I do???
