Subway complaint: Charged for Food that I never recevied

On Friday July 17, 2020 I ordered from the Subway at 1033 South Court St. in Medina, OH.On the Subway mobile app. Soon after I ordered a gentleman that said he was the manager said that they could not complete my order because they were out of product and that my order would be voided and not charged. On July 20, 2020 I noticed on my bank statement that i was charged for the food and it was never voided. I called the store and spoke to the Manger there at the time, she said her name was Jennifer. I advised her of what has happened and after she complained about how she has to train new people at her store, which is not my problem, she said since her manager did not void out my order the day it happened should could not issue me a refund. I was not happy about that and to be honest that did not make sense to me. She offered me free food instead but I advised her that we were visiting friends in Medina and I do not live close to them so I asked if they could issue me a gift card and mail it to me. She then responded by asking how she was supposed to mail it to me, and she said this with a very mean sounding attitude. I advised her the post office and she refused to do that. We kept going in circles on how to resolve this and she kept blaming her new staff that is not trained properly which again is not my problem. She finally said she would ask her boss and call me back. She did and offered me a gift card for $25.00 and a free sandwich that she again told me I had to pick up in person and apparently she was not listening before when I said I do not live close since we were visiting friends. I advised her I would have my friend come up to the store and pick up the gift card and since she could not mail it to me my friend would be doing that. She agreed to have my friend come up there. My friend then went up there 4 different times for the past month and each time he went up there they claimed that their credit card machine was down and could not issue the gift card. For the past month they have been claiming this and my issue has still not been resolved. I am avid customer of subway in my area and i’m very upset that one of your franchises are representing you like this and would like my issue resolved immediately!!!!!
