So, how is it different that at a DC? In both cases you walk up to a car that is locked if you haven’t paid. You need to pay to unlock. Exactly the same. The car doesn’t care where it is when you pay. Just that up you have to pay before unlocking.
#1 - it is good you are here looking for advice/complaining
But…#2, it is bad that you didn’t come here before you ordered/paid and read all of the guides on what to do. The most important thing, is do not pay until you see the car.
