Received call from Joseph Catona (?) who said he was calling from the National Process Services Dispatch Office and had legal documentation associated with my name and social security number.  Documents would be served on 1/23/15 unless I called him at 210.774.4142. Called my local phone service operator who told me she had never heard of this service and that the number was not a working number.  Told me to disregard the call and do not call back or provide any information.  Is his a scam???
