Goodwill Industries complaint: Humiliated accuses of stealing for no reason

I brought my service dog into store looked around took several items to try on in fitting room exited fitting room out clothes I didn’t want on rack started to look more but puppy was acting up so I went to sit outside to wait for friend who was still shopping few mins later a guy walks up to me and said I need to leave, I said excuse me he gets louder and says I have you on video stealing z to leave. I told him I’mI didn’t even take anything n he was mistaken, he then said I’m trying to be cool snot this now leave. I said I was waiting for a friend and hadn’t done anything wrong he proceeded to get louder and say ok then I’ll call the cops and say I was trespassing??? I asked trespassing for sitting out here really? He then walked off to go talk to 2 female employees that were in front of store smoking. I was completely humiliated and embarrassed at what and how he was being and what he was accusing me of.. I absolutely love the store I have 4 teenagers so very helpful financially but do not want to return there and be falsely embarrassed again.
