Subway complaint: Online order

I ordered online. Arrived at pickup window @7:55 pm., correct time for pickup. Was ignored for 15 minutes. Called girl and 2nd attempt answered. Told me to wait 20 minutes as she had other customers. She was very rude. I had to wait an hour in cold car as had paid when ordered with a tip. Got it at closing after calling her again. She did ask if I wanted her boss’s number, yes, well I don’t have it. She was cleaning and emptying containers to leave. Requested for meat to be heated, wasn’t. My husband is very ill; therefore, we only do pickup. We are in our midlate 70’s. Sandwiches were terrible and threw in trash as worried about eating them with left over scraps. She didn’t give a receipt, to hide the time we had to wait. I will never go there again and advise anyone elderly not use this location. We want our money back including tip and extra for the treatment we received from this person. This was elder abuse to force us to sit at the window for over an hour to get what we had paid for. We had to sit there and watch her talk and give other’s their order while we were ignored. No one should be treated as we were for a paid order.
