I have received calls from 978-515-5580. They tell me that they have not been able to locate me (although calling my cell) indicating that there are legal docs that are un-deliverable as a result. They provide a case number and another phone # to call for more info. When calling the ph # provided, they claim to be from the Law Office of Cowen and Beck with a case that is in litigation but want to talk to me before sending to courts and will NOT tell me anything without verifying my name, SS # and birth date, which of course I refuse and then they hang up on me.
