Who called from 9284448675

Got a call from this number, but since I didn't recognize it I didn't pick up. No message was left. When I called it back (masking my number) I got a message that said "this number is not assigned". So obviously this is a SCAM! Number blocked!

Called my business and when I answered it was an automated goodbye. Not sure but has called a few times.

Auto dialer.... scammer, return call results in "number not assigned yet"

Called but quiet for a second, then the echo of a call center, then foreign sounding "Hello..." ... and then I hung up.

Scam they say they ask for an owner or manager then when you ask why they state its for work place health and safety I told him I could help he just started acting confused then I stated I was a manager and he hung up on me. I called the number back it says its a non working number. I'm guessing it's one of those make you think I'm osha and take $250 from you every month for knock off osha posters.
