On Monday, I received a pink postcard that wanted my name and birthdate. They said Medicare and Medicaid recipients who may be eligiblefor dental and vision coverage at no cost to you. It was from PO Box 2528 Rockwall, TX 75087. The. It said they have reliable information. They are not affiliated with US government or state agencies. Why send back. They already have my name? Birthdays and any soc Sec numbers should only be given to banks, health insurance brokers, etc. I cannot see why my BD should be included. Any thoughts????.
