Dollar General complaint: Bad service and attitude

I went to dollars general store in Semora, NC on March 9, 2022, and purchase a cheeseburger out the frozen food department and the price on item quoted $1.00 and was charged $1.50: went back the next day to let the young lady know that I was overcharged, she got smart and said that it was not her job to change prices it was her manger Barbara to do that then she reaches in cash drawer and hanged me $.50 back. I went back again on 31122 to purchase another one because it is a convenience after working in yard all day not having to cook. The prices were still 1.00 and the girl rang up $1.50 again she ended up with a nasty attitude and gave me the burger (which was totally inappropriate, because if an audit had been present when I walked out the store with it I could have been arrested for a $1.00 cheeseburger. I told manger the very next day and she acted as if it was okay. I offer to pay for it but she refused to take it. The principal of the whole thing is if you got someone working with an attitude doesn’t need to be there. The prices need to be the same at cash register as on shelf and also find better workers,
