Family Dollar complaint: Sales associate

I came into the family dollars to purchase a couple of items. Which one item wrong up incorrect therefore I ask the associate to let me show her were I got it from because there were others like this item. The dish detergent ring for 8.75 but it was on the shelf for 4.00. She started that “ we not changing any prices”. So I asked her was she the manager she said no so I asked for the manager. She walked off and curse “damn lady why can’t you just shut the fuck up and listen to what I said” she started hitting her hand then saying this ain’t what I won’t I ask for the manager. The manager ever came to see what I where taking about. Therefore I went back to the register where now the manager is there she was very more polite. And assist me without the shed price I feel in customer service no one should be treated like I was on 4112022 spending my money I really thought she was about to hit me I am 51 years old and this young lady liked to be in her twenty again no one should have to go through this abuse
