Food Lion complaint: Items not received

On Sunday, October 24, 2021 I was shopping at the Food Lion at 570 Riverbend Dr, Charlottesville Virginia, after paying for my groceries which rang up at $113.10, the male cashier started putting my groceries into the shopping cart, I remember putting a couple bags into the cart. I then went to my car and put all (approximately 10 bags) bags into the trunk of my car. Once home I unloaded all bags, inside my home I put away the groceries, not paying any attention that I was missing a bag which contained frozen stuffers Mac and cheese and a half gallon of food lion napoleon ice cream. It was around 11:00am when I started to prepare my dinner that I realized these items were missing. I first went back to my car just to make sure I had not left it. I then called the store and spoke with a Customer Service Rep, she told me she would have to get back with me once she reviewed the tapes. I headed to the store as I live only 10 minutes away. I told the girl who identified herself as a CSM, why I was there, she then goes to the back to view the cameras! I had by then got another Mac and cheese and ice cream and repaid for it. The CSM comes back to me and says she saw me take the bag and put it in my basket! My question is, how can she say she saw me put that particular bag with the Mac and cheese and ice cream in it, in the basket IF I had other bags as well! The cashier had put most of the bags in the basket! Then once I was home, I get a call from Tameka who identified herself as Manager, she basically told me the same thing, what they say the cameras saw me doing!
My biggest complaint is, as a Loyal Customer, the employees are basically telling me I am lying about not receiving my items, because the cameras say I put the bag with the Mac and cheese and ice cream in my basket! I am a 72 year old retired senior and I am honest.
