Do you get these calls?

For the past several days, I've been getting one or two calls from people (apparently in India based on their accent) telling me they have a new "medical card" waiting for me. At first I just hung up, then after I got a couple more I decided to play along and see what this was all about. Not possible, for the guy named "Mark" apparently calling me from India, could not answer any of the questions I had for him. The toughest for him to answer was when I asked, "Why do I need this card and what will it do for me." He stumbled for several seconds, before I started to laugh and then I hung up. I suppose there are enough gullible people in the U.S. who really like to speak and do whatever business might be desired with "out-sourced" people like "Mark", such they he and others keep calling us so many times. Sad times indeed.
