Roses Discount Store

On Oct 2 2023 I purchased a skirt from this store. The skirt was 9.99. It was on sale for 5.00 then 50% off of the sale price. I noticed when I got home I was charged full price. I called and was told to bring it back. It was before the 30 day limit. The cashier tells me she cannot refund the 7.00 nor let me get anything in the store for my overage.
