Goodwill Industries complaint: Rude store manager

I was going to buy a picture for 29.99 and I turned the picture around and the original nee price was 19.97 so I asked to speak to the manager and see why a used item was priced $10.00 more then the original new price. She came out and looked at me and said O well who ever priced the picture thought it was worth more them the original price. I said wow so that’s it and I said obviously your not comprehending what I’m sasaying. She flew of the rocker following me around the store saying I’m the Store Manager I’m the store Manager what store do you work at, has I work at the goodwill on peach orchard threating me She is calling my manager I’m a paying customer who doesn’t deserve to me talked to like that or threaded about my job over a mistake on a price that I brought to there attention.
