What kind of company sells art supplies, medical items, and printer ink and toner? What kind of company has to keep changing their name - United Business Supply, United Art Supply, United Business Source and now Kleritec? They are all the same ruthless scammers! They prey on new employees, lying about what their predecessor did/did not order, or employees with no authority to order anything. They lie low for 6 months or longer till you forget what dealings you last had with them, then "quote you " what some invoice supposedly said, and you ALWAYS owe them hundreds and hundreds of dollars that are a surprise to you and continue to send boxes of stuff you NEVER ordered, and can't send back! Keep every piece of paper you ever get from them and don't order anything over the phone - that's how you have no proof. Even when you demand to be removed from their lists you will get a call months or a year later starting up the same old thing AGAIN , trying to say you still owe them money!
