Family Dollar

Went in to buy a mattress cover. Clearly posted 6.25 for a queen. She charges me 10.00$ I walk back took the picture of the price posted. Nothing back there is posted 10.00$ Nothing. She said she knew it was posted wrong. Told someone to go fix it and refused to refund the difference to me. I was like are you serious?. She said she is to busy to deal with me while she stocking shelves. She wouldn't honer the price. I shop there all the time. She is rude and treats her employee the same. No respect. So she clearly lost me as a customer. I hope this isn't how you would treat a customer. Clearly I asked for my money back. Lose a sale.
