Order issues

I placed an order online and chose to use the pay by card on delivery. After waiting about 45mins,which is how long it normally takes for delivery, I can the branch and ask whats going on with the order, is there a mistake or what. They tell me due to them only having one card machine for delivery, my order is delayed. Now I think it's quite obvious that I'm not at fault here. This is the worst service yet and all that I got was a manager that doesn't respond when she's spoken to and when I told her I will not be paying for the order, she said that's not her problem, the driver will need to pay for that. I don't think so... Store manager should be held liable for that as it's not the customer nor the drivers fault that card machines for delivery is scarce.

And 2 hours later.. No order has arrived. So as I said to the manager, I will not pay for an order that's 2 hours late.
