The Salvation Army USA

I purchased a 4 piece canister set from the salvation army on 823 E Auburn Rd, Rochester Hills, MI 48307. The manager who rung up my order placed my canister sets in the box without wrapping them in newspaper, when I arrived home to clean my canister set I noticed a crack that wasn't there before. The very next day I went to return them with my receipt and the same manager reused to return my items because of the return policy. But I informed him that it may had been his fault for not wrapping the items before placing them in the box. He still refused to return my items and he proceeded to argue with me infront of customers he was very unprofessional.
