Camera Center Inc. Deceived by two salesmen Orlando, Florida

I was on vacation and wanted o buy a 400 mm lens for my D5100 DSLR camera. I was unfortunate to go to Camera Center in Orlando. Those two guys were having lunch, and when I asked about the lens the short Italian guy came to service me. During the process, this old French guy started to demonstrate some accessories for my camera, like filters and a wide angle Axer Lens. He said that this lens was priced over $1300 and that he would give me discount because I was buying an expensive lens. I dind't want to buy, but he was so insistent and kept reducing the price that I accepted and and bought it for $500!!!

When I got to the hotel and searched it in the Internet, I saw that the real price was $20!!!! I was so mad that I called the store and they informed that all their sales were final, they have a non-refund policy. They even showed me an internet address, where the price of the lens as showing $1699!!!! The site looks like a fake, and those persons are crooks and deceivers, they should have been put out of business a long time ago! I have been searching at the internet and I foind hundreds of complain abou this store! Why the authorities still accept this kind of behavior? Those guys should have been out of business for a long time...
