They have been persistent - I never accept the call from this number but it logs in on my cell phone. Calls began on 7/22/2016 and to date (7/26/2016) I have received 8 calls. I am a senior citizen and I know these scams are normally aimed at seniors. Wondering how many of those replies above are also seniors. I plan to perhaps answer the next time and after they start their "schpiiel" I will advise them that they are speaking with the U,S. Attorney for the Southern District and I plan to locate and prosecute them.
