Tech Support Scams

I received a call telling me my computer is being hacked and I needed their help. They had me run programs telling me to look at files that have stopped and I was being hacked. Then they had me type In www.teamviewer to download, I told them I would not until I researched who they were and hung up. I said How do I know if your not the hacker. A minute later a "superviser" call and said He would hold on while I researched their site, I said I was not going to sign up for this program and would do further research on their business, he then threatened to report me to the FBI and have me banned from the internet for life and was very threatening and yelling at me and I said if anything happened to my internet I would report him and he said he was going to report my threat to the FBI again and again and make my life a mess. He has my address, name AND ID to my computer.
