This company sent us products at 2 of our locations with out an order from us. Then argued with us about it, saying we did order it. We have never ordered a thing from this company. We are a couple states away. They couldn't prove delivery of the items and then also stated that they wouldn't take the returns. $15.99 for a can of penetrating lubricant. I certainly think not. Only one location actually received the non-ordered product. We will be returning it to the ship from address and we will not be paying these invoices. We have now black listed them in our company to make sure we never give them any business at all. I work for a large company and I do business with hundreds of vendors and I have never come across such a horrible business.
