Gutter Experts Non Payment savannah, Georgia

Gutter Experts ordered an advertisement from my company and refuses to pay now that the invoice is due. I personally spoke to the owner Derek Adams. He placed an ad with me. I told him the advertisement would be ready in a couple of weeks. We created an ad based on the information he provided and printed the advertisement. The finished product was delivered to him by the delivery person. He promised to pay MANY, MANY, MANY times. I have called and was told that payment was on its way etc.. We are still waiting for the payment 90 days. We Created an ad for him at no charge. Printed the ad, created a TV spot for him as well. Beware of this company. You may have heard of him through our advertising efforts, something he has taken for free to this point. I wonder how he would feel if we asked him to do work for free??? He expects everyone else to.
