I have had a frame shop since 1983 and for the first time I had an order cancelled after I ordered 3 chops for oil paintings. The job is for over $1,000 or I would'nt persue this. I do not have the art in my possession, and I did not get a deposit because the person who placed the order was acting as an agent for a company. I now know to get the deposit befor ordering chops. What are my legal rights to collect on the unpaid invoice?
