Family Dollar complaint: Moldy tortillas

Went in on Sunday 115. Grabbed 2 packs of tortillas. Ran in, ran out, no problem. Get home BOTH packs are moldy. 🤢
Thought okay nasty but I’ll take them back get my money, move on. Wrong…..
Sherry the self claiming store manager was behind the counter as she was when I bought the tortillas. I went to the back off the line waited my turn, came my turn gave her the moldy tortillas. She said oh my God, and instantly began to start a refund for me. She said do you have your receipt? I said no, I think you threw it in your tash. She then digs threw the trash. She said she took it outside and she doesn’t have my receipt.
She then says she could refund me on a gift
card. I explained to her that I didn’t want a gift card, because I didn’t want to buy food from there, due to the obvious.
She said she could give me a cash refund but she’d be in trouble, because the refund amount was over 5.00. ( my total was a whole 6.24)
She then became aggressive and threatened to call the police. Also another woman in line began to tell at me and my daughters. The manager just kept yelling. At one point she even started to slide a gift card. I told her this was all not expectable. She then told me it was my responsibility to check the food before purchasing. She offered to finally exchange the tortillas. Embarrassed I expected. I took the tortillas and left, and when I got home they were also expired.
I cannot believe the level of embarrassment over this very rightfully and small refund.
I would be absolutely concerned for my store if this was the manager running it.
