I received a call from this number and they asked for another person, I told them they had the wrong number and they said "actually we are trying to reach this number because I have won a sweepstakes". Obviously, I cannot be the winner of a sweepstakes I have NEVER entered.
Got three calls today from this number. No message left, return calls are disconnected immediately upon connecting. I suspect this is a way for scammers to verify a phone number similar to phishing.
