Dollar General complaint: When did Dollar General start not allowing you to return unused unopened makeup

I returned a few item to store 15292 and when it got to the return of my makeup Fanny the cashier told me that it was not part of that transaction I had the receipt for I said yes it was she said no it’s not you are not returning the makeup,. I paid with a debit card and the money had already been taken from my account and I requested to have cash as my return and she rudely said no your not getting cash it is mandatory to go back on your debit card and if you don’t have your debit card I am not giving a refund for anything, I was already pissed about the make up I asked her so where does it say any where that unused unopened make-up or any make-up at all is non returnable or refundable, and she replied your not allowed, so I said whatever and put it back on my debit card, left registration went and purchased cookies and milk my boyfriend after it was rung up and I had my debit card that money should of been put back on to pay started walking towards the door and she said where is he going you can’t just take that and we weren’t I was paying for it she treated us like we were criminal and I will never shop there again and I’m putting this all over social media about the stores rude unhelpful employee
