I am getting calls from this #.

I received three calls today. First one I answered; the individual asked for me by name and stated he was calling about an auto loan (I have not applied for an auto loan in decades). I immediately put my phone on speaker and muted the mic button and waited, about 20 seconds later the man hung up. He did have an accent. Received two more calls and repeated the process.

The first number 813.574.2608 and caller ID was from Tampa, FL. The next two calls were from 401.648.9484 and caller ID stated Not Available.

I've received 12 calls from these idiots in the past 2 hours. They hang up when I answer.  
Think I will start calling them every 5 minutes

Keeps calling knows my name and says about car loan then hangs up

I did block the phone number on my 10 year olds phone that they keep calling, unfortunately they then change the number and call again
