Family Dollar complaint: Very rude

About a month ago I went to the family Dollar here in Athens Wyoming and bought two packs of cigarettes one camel blue and one marble light I got to my truck and I asked my boyfriend to look the receipt cuz I thought he charged me for two packs of camel blues and it was on the receipt that I was charged two packs so I didn’t even leave the parking lot and I went back in got in line and said you charge me for two packs of marble blues and you only gave us one so they gave me another pack of camel blues today on 9162020 I went into the store who I cigarettes and the cashier was very rude his name was John and refused to sell me cigarettes saying that I accused him of charging me for two packs of cigarettes when he did I gave him the receipt in the first place I would not have went back to the store if I wasn’t charged for two packs and only gave one that was his air his fault not fine and he was very rude and refuses to sell cigarettes to me anymore from the store so I can accuse him of overcharging it doesn’t look good for your company to have somebody like that it was his simple mistake not minewhat makes me even matter is I buy my cigarettes from family Dollar all the time I purchased them in cartons and packs and he has also sold me packs since this incident happened and then today of all days he accuses me of accusing him of overcharging me you guys really need to get some better cashiers that know how to do customer service
