Dollar General complaint: Faulse accusations

I went in this morning and tried to return some medicine that my husband had purchased Friday evening when he got off of work. When I went in there the lady had first told me that they caught my husband stealing a pack of gummy bears searched him and told him he was not allowed in the store. So I went home and I got my husband and brought him back up there so the lady could see him and so that I could prove that it was a false accusation. Upon returning with my husband the lady says, oh no he is not the man that I caught stealing gummy bears. I did not search him but I did tell him he was not allowed in the store ever again. which was also false. If he was not caught stealing and he was not the one you searched then for what reason do you have for saying that he was not allowed back into the store. That’s besides the point because the medicine had nothing to do with gummy bears. They kept my medicine and would not give it to me because it was possibly stolen. They have no evidence of this and I know for a fact because it was not stolen. So how do they have the right to keep something that I purchased without any evidence or proof of anything. Now I am out of 30 bucks because one of y’all’s workers obviously confused him with someone else. now we are both not allowed into the Dollar general store because of this. I am furious. This is not right I will sue if this is not resolved. I will not have my name nor my husband’s name lied on. Now I will be inconvenienced and have to go clear across town to get something from the dollar store. I go in that dollar store every single day and purchase things I have for years and never had any issue until this lady decided to lie on my husband. I’ve been with my husband for 22 years and I know for a fact if he says he purchased it, he purchased it. But that is besides the point if they feel it was stolen present me with evidence which I know they cannot so give me my stuff back or my money and lift the order so that I can use my local dollar general again.
