Evolution Inventions Peter Sinclair Where's my patent? I PAID IN GOOD FAITH. Internet

I have an invention that will save lives and should be fitted to every motor vehicle. It should be MANDATED in any country where motor vehicles drive on the other side of the road to where it was designed.
I lodged the invention with Evolution Inventions and agreed to pay a monthly fee. They undertook to sell my invention at Inventors' fairs etc, to their customers in China and pay me royalties.
They were responsive at first then about 4 months into the contracted timeframe they disappeared.
NOTE! They were always difficult to get a response from.
Peter Sinclair was polite and always helpful, until he decided the scam had made enough money.
