Simple Site Paid for Blog hosting - site doesnt work Wont respond to customer service complaints Capital Region

Ipaid for a blog site domain a week ago and now it somehow says site does not exist. My site was about a carvsales and finance company named CARHOP that preys on people with bad credit that need a car. So CARHOP sells them cars at 3 to 5 times what Kelly Blue Book says they are worth. The cars are junk and fall apart. My son bought a 2007 Ford Fusion with a 142,000 miles, non working radio, bald tires, loose door, and a power steering pump that was going out. I got an email about a review with the name Jack me Off saying just bought a car from carhop will go back. Obviously a carhop employee. I am of the minset Carhop contacted simple site to have it shut down. They have been paid for the domain and hosting yet it is down and when i try logging into my back office i cant. Simple Site does not respond to emails and now their email keeps kicking back as the email is full and they dont answer. USE (((REDACTED)))!!!!
