Habitat for Humanity complaint: Selling an item out from under me

I called to find out if a certain recliner was still there the gal said yes I asked her to pull the tag and I would be there by 11a.m to buy it so she did. I was there before 11 and noticed some lady put a sold sign on it I asked her what was going on and she had said she just bought it from someone else that worked there who had no right selling that when someone pulls a tag it means someone’s buying it already That girl who was selling it to me was on a break when all this happened . I was livid the lady who bought the chair was gonna get a refund but the girl in back who prices things told her no cause she was first.I HAD THE TAG SHE WENT AND RETAGGED IT FOR THAT LADY. So I had to leave before someone got punched. Who the he’ll is she to tell that lady she could have it? When my lady was on break? I’m beyond pissed I will never donate another thing neither will anyone I know. And I will never buy anything there again. Your company is not running fair. At all! If there was no holds on anything why doesn’t someone post a sign? It’s pretty sad when the cashier has my tag and I’m still looking around only to get screwed over by some freaking bitch that is not even the cashier.I will never talk nice about your company ever again. And by the way the girl in back had no right to intimidate the cashier that was holding it for me.. I am sending this also to complain.biz
