They have called me now about 3 times within the last 10 minutes and will not leave a message. I will not answer any calls I'm not aware of and do not know how they have my number since I"m supposed to be unlisted. When you try to call it back, it goes to voice mail and only indicates that you've reached the reception desk and to leave a number. It does not specify any particular company.
I called the number back - it's a fraud scam pretending to be Wells Fargo. The number is to a company called ACO - which appears to be a fraudulent attempt to gain personal information.
Fraud scam portraying themselves as Wells Fargo. Number belongs to a company called ACO which has a recording indicating they are not the ones making the calls.
