Recent caller, leaves no message. After I blocked the number, I dialed it. You get a message that the number is no longer in service. So, you can be 100% sure this is some of sort of scam or fraud.

4 second blank voice mail. This call didn't ring. Not in recent calls list. It went straight to voice mail. Weird.

Canada Pharmacy scammers. Don't answer or just hangup

I get a phone call at least once a day from this phony company, also one from "U.S.  Pharmaceuticals (pretty sure it's the same phony company, just different number and uses U.S. Pharmaceuticals instead of Canadian Pharmaceuticals)... Today's U.S pharmaceutical caller's name was "Alex", sounded like he was from India.
