Suspension won't pump up after tires put on

Had new tire put on yesterday and I turned
suspended off before they started. When they
were done I turned it back on and it wouldn't
pump up. I did everything I could find and even
stood on my head and nothing worked but I
could hear it trying. Could they have damaged
something yesterday because I did hear a
fudge bang as the where lowering the jacks on
each size of the car. Shouldn't they be
responsible to fix it because it fine and had no
problems prior. I only have 60,000 miles on it.
