St Vincent De Paul complaint: Wouldn’t sell me an item

I went to the st Vincent DePaul store in Monroe . Found a few items and a pair of Jeans my partner separately needed . I accidentally pulled the tag from jeans upon pulling out of my cart . Old woman At the register said the tag did not match the jean size she then proceeded to tell me she will not sell the jeans to me I asked if I could speak to a manager she refused and told me that it was store policy after asking if someone could please just put a price on them she called up management they again tried to tell me they can’t sell an item without the tag attached I asked again if they could price them so I could buy them they refused I asked why I could not buy them and explained again that I desperately needed them they then told me I would have to come back tomorrow to be able to buy them . I live 45 min away so me coming back to get jeans is ridiculous The two women then went over to the rack of jeans found a random price and tried to charge me $10 for a pair of jeans. Upon frustration I denied making the purchase and left the store
