United Patent Research Selling me a patent knowing it would be invalid Olney, Maryland

I called United Patent Reseach in 2010 to help me patent my plant support called the tomato cradle.They wanted $790.00 to do a patent search,which I gladly paid. When they told me there was nothing else like it my wife & I decided to go for it! I told UPR from the beginning that my father & uncle had made these plant supports 30 years ago for their own personal use but never wanted to patent or sell them. I wanted to sell them but needed the patent protection UPR promised me.They needed $9,975 to continue the process which I paid. A year later I was issued a design patent & was told everything was good. In the meantime I have invested well over $2,000 in patent agents & help to get my product licensed only to find out my patent is invalid because I was not the original inventor! I am fine with that,but why didn't United Patent Research tell me right away that I could not patent my product because I did not invent it! They wanted my money & once they cashed the check they did not care! I know for a fact I told them the story about my family but of course they denide everything! So I guess it comes down to I said-he said & I know who will lose out there! I don't have the money to hire a lawyer because they robbed 75% of my retirement savings.I know I will never see my money again nor am I looking for sympathy,I just want the world to know about United Patent Research,thank you.
