A.A.A. American Flag Dec Co. Inc.

I provided a service to this company and sent them merchandise that is not resaleable, due to printed banner for a business. The customer was unable and was extremely rude when he called about the merchandise. I misunderstood the orders and it was printed on a different material that I took as what he wanted. After speaking with him that afternoon he put a stop payment on his check and is not willing to pay for the product that I cannot use. The cost of the banners were 540.00 plus my bank also charged us a return check fee. He tells me to stop moaning. He has been extremely unprofessional and rude. He has had the product shipped to his customer and has had the product since before Christmas 2013 and as of today 1/**the customer still has possession of the artwork.
