Who called from 7206856301

Rings several times then hangs up + leaves no message = goes on the blacklist

Missed call , no message left.

This is just one of many different numbers calling me with the same thing happening:

When I pick up, they ask to talk to "the business owner" about some opportunity. Whenever I ask for clarification or to stop calling me they just hang up.

Phone number  is  disconnected. .. stupid.
