I too run a professional business and my business received one call from them the same day you did. With my business phone system they didn't get past the Auto-Receptionist since it will hang up on them after the welcome message is played three times with no menu option key press. They never got a chance to leave a message. That functionality is great when it's a robo-call since robo-calls can't select a menu option. I then Google the number (and usually end up here at "800Notes.com") and block them. If they call again all they hear is, "I'm sorry, the number you dialed cannot be reached from your calling area. Goodbye."
Got a call from this number stating I could be eligible for a 250K Business Loan for my Business.. I don't own a business. I asked the representative how they got my number and he hung up on me.
"Hi this is Howard from the loan department..." Hung up after that. Have gotten many of these calls from different numbers over the past several weeks.
