It's BECU's loss management number. I got a call from them asking for the former owner of my cell phone's number. Since the call fit the profile of many of the calls I receive for this person, I am confident it's legit. It was not a robo call, but a live person. They removed my number at my request.
Not sure why this company called me at work on a Saturday. I left a message for whoever left me the message to call me back. Will advise you if that will help you in your quest.
The recorded voice idenified itself as BECU, and said "call this #, it's important." My husband has an BECU account. He went BECU, and asked about this call. The BECU teller told him, the # is scam, nothing to do with BECU.
