Family Dollar complaint: Racist employee

Store employee has showed past racist behaviors toward my family members prior to this incident. Family members enter the store and purchase cigarettes employee gives them the wrong cigarettes in which they asked for gets an attitude accuses family member of slamming their phone down on the counter then tells family member to leave the store.Family member asks for his receipt.Family member leaves and I come in the store with the unopened cigarettes employee is already on her cell phone talking to a manager accusing the family member of slamming his phone down and and trying to exchange the cigarettes.I have changed cigarettes at this same store previously twice with a different employee at the store which I explained she just kept interrupting me and telling me to get out.I asked for a refund was told no and told by law it was illegal to do so I ask to exchange the cigarettes for the right ones and also told no very loud and rudely I told the employee I was calling corporate and proceeded to walk toward the exit and she started back and forth with me about call corporate she doesn’t care and telling me to get out the store she was calling the police I guess because a black person got loud when she started to get loud and disrespectful which she had no right this same employee has prior to this incident showed previous racist behaviors really can’t believe a business could employ someone who exhibits this kind of behavior such a shame.
