Business ProfileforParamount Ghostwriters

I paid this company to write a book, publish it, sell it and print it plus promote it. They claim they are in LA but I found out they are in India and Africa and scamming people. I was foolish to pay them money. I have spent over 8k with them because they make it seem like they will work with you and deliver. So they did write a book, which took them two years because I kept pushing them. The deal was suppose to be completed in 3 month and took 2-3 years instead. While we were writing the book though they sold me a bunch of promos like printing more books and making my book best seller etc. So I paid them more. Three years later I did get a book they wrote but never got the promotions and never receive the books printed that I paid for and they of course didn't promote book or deliver on any of their promises. I want everyone to know they are a scam and they are not in the states but in fact overseas since when they called me or worked on anything i was able to track them down with their phone number and ip address. Also I gave them access to my social media and to see if they would help promote and the one time they signed on I got a notice from FB that someone from India was logging on. When I confronted them they denied it and then we tried again and then someone from Africa tried. That is when i knew they were a scam. Please help to see how we can cancel their website and stop them from doing it to others. They also have other sites they have created and have a bunch of usa numbers because they also do not stop calling me trying to offer me more deals and under other names. Thank you,
