Falsely Accused of Shoplifting

So today I went into the same Countdown I had been going to for a few years, and that I usually go to 2-3 times a week, if not more. I was approached by a security guard, a male employee and the female manager a couple of minutes of being instore. They informed me I had to leave the store immediately as they had said to me I had previously been caught shoplifting about a week prior. I was so dumbfounded and embarrassed. I firmly denied this and told them I could produce evidence of my bank statements online to prove I have paid for everything I have ever purchased at the store. I asked them what so-called proof they had as I would be demanding an apology because they had the wrong person. They showed me a photo of myself entering the store and a photo of my car that they had put in the system. I confirmed to them that it was me and that it was my car. I then said well where is the evidence of me actually stealing like you say I have. They then said there was video evidence, and I kept saying where, and wanted to see proof. After they had watched the video footage they realized they had wrongly identified me as the theif and then started apologizing saying it wasn't their fault. I was mad as hell to be accused of a crime I never committed, and yes I did say, "do we all look alike to you? because I'm brown skinned". I told them whoever it was that identified me as the theif wasn't able to tell myself and the theif apart, really? even though the manager and the other worker could after viewing the footage, is where the fault lies. That person and your security system failed, like don't other people in the company make sure things like this are done diligently or if anything is double-checked to avoid this sort of thing from happening. It's so poor from Countdown, DO BETTER!!! to make sure this kind of thing never happens again. It's a serious offence to be committed of stealing from a store. I have now put in a complaint, and hope I have not been reported to police or I am in the system as that is something I would have to sort out by being falsely accused. Just wasn't the day I was expecting 😕
