FLAG THIS: Due to changes in Medicare due to having validated social security numbers affixed - they now have an ALPHA-NUMERIC (Letters & Numbers) ... THERE ARE SCAMMERS, HACKERS, ETC - Who are calling people to tell them their new Medicare or Social Security Card has been compromised. DO NOT ANSWER SUCH CALLS... If you feel that there's a problem go to medicare.gov or socialsecurity.gov and call them directly. SOCIAL SECURITY AND MEDICARE WILL NOT CALL YOU .... UNLESS YOU CALLED THEM AND THEY ARE RETURNING YOUR CALL.
