Every day about 3-4 times a day I get a call from these people I wish they'd leave a message! But I know they're just fishing..

I have been receiving calls from this number but they never leave a message. I finally picked up and the caller claims there is a warrant for my arrest for tax fraud. Clearly the call is a fraud. When I tried to call back, the number is not registered to anyone. Wonder why they don't want to be identified. Probably fraud!
