Yep, same thing here and we get these types of calls quite often. This time someone calling herself Gwen Morrison called and left a message using my husband's name and saying that they are attempting to serve a court summons for attempt to defraud a financial institution. Then they give this number to call back "the attorney's office" who is handling the case - complete with "case number" (which isn't the right format to be a genuine court case in the area where I live.) To begin with, no one calls to verify your address in order to serve a legitimate legal summons. They HAVE that info if they are for real and they just show up at your residence or place of business. Secondly, what legitimate attorney's office has an 855 number? They have ACTUAL phone numbers that go to ACTUAL offices.
Just another collection agency attempt to make people think they are somehow affiliated with the courts when they really aren't.
