Got a call from them I picked up and no one seemed to be on the other line, but they hung up after 10 seconds of silence

This number came in as Healthy Blends USA and wanted to talk about combining natural foods for better health.    I answered because the call has shown up a number of times identifying as Dir Assist TN.    Once they identified themselves and what they wanted I hung up.

Didn't answer...  Blocked call.

Called my cell but I didn't answer.   Didn't recognize the number.

Called my cell twice so I blocked the number.
