I got a call from 3604607730 while I was working with a client. It was very distracting. I believe they may have gotten my number off one of my websites where I get leads for new clients, as I belong to the Zumba instructors network, and I was warned they have been targeted recently. I didn't pick up the call, but when I tried to call back, I would just get cutoff, and then I may have been blocked by them after a few minutes I called them again and it said the number had been changed.
