Can’t get help from anybody at Subway

So my wife had placed an order at a subway that was nearby. She had placed it online and the money was withdrawn from our bank account but when we get to the location, they tell us that they have no such order under the name or anything of the sort and they really told us they can’t help. I tried finding a corporate number, but they are pretty much nonexistent. I tried looking up corporate headquarter locations, and the one in Florida apparently doesn’t exist because when I try to search up the address, it takes me to a permanently closed location in Connecticut and when I try to call the number to the location in the Connecticut location that is supposedly still open it rings once and then disconnects immediately, but it shows it’s a number for an actual subway restaurant location. So I think they are purposely hiding all their information because they don’t want to help anybody and from what I can find there is no information online to contact any type of franchise owners to get a hold of them to figure this out. The order was for only $20 but it’s the fact that the order was placed, the money was taken out of my bank account but here I am sitting at home with no food that I paid for. This is more of a rant than anything else because I am so frustrated and fed up.
