Is a stop payment on a check considered a criminal or civil offense?

Question Details:

My daughter found the wedding dress she wanted at a store. We signed a contract whereby we gave a check for 50% deposit and signed an agreement that said we would pay the rest when the dress came in. After we left, we heard some things about the store and decided not to buy the dress there. We went the very next morning and asked for the check back. The store owner was rude and said no. They had not ordered the dress, so we put a stop payment on the check. Now we have received a notice saying we have violated OCGA16-9-20 & 13-6-15. Is this true? We received no merchandise.
