Family Dollar — Falsely accusing of stealing

I went into store on 12-15-21 to purchase something but did not see what I wanted so I left store and as soon as I was outside the store I took out a drink that I was drinking through out the day and started drinking and I saw man and the manager Rosa Rodriguez approached me saying that I stole a drink from the store and they saw it on the camera.I told them that I did not stole anything from the store and that it was my drink.They created a scene outside and embarrassed me in front of everyone. They then left and went inside store so I called my dad and he came and went to the store manager and she said yes I stole a drink but she did not check the camera so how does she know,then after a while started saying that she’s sorry but kids always come un store and steal things .I told her that I am 18 years old and I have my money.My dad ask to see the camera but she refused to show him and keep giving attitude and saying that I should leave my book bag at the front when I come in next time .How can you accused someone if stealing without evidence?Rosa should not be a manager as she’s very unprofessional and doesn’t seems to know how to go about complaint made by employees instead she just came and accused me without checking the camera. Why didn’t they call the police ?since I stole a drink and they saw me on camera.would like this to be looked into ASAP and there should be consequences for these behaviors. Thanks
