I get these calls almost daily and I never answer. We DO use Medco so I am not sure of the validity of the calls, but today I pressed 'talk' to see if I could actually talk to a real person. After about 20 seconds of the robo trying to connect me, it hung up. So since the federal DoNotCall does not seem to work, I am using all of the technology available to combat this caller (and others). My Panasonic phone system has a built-in caller block that you can block the number with only a few keystrokes. That is the best that any of us can do since the government and phone companies are unwilling to help John and Jane Doe in this blatant form of phone and privacy abuse.
Oh, and I believe that MedCo is asking a survey question to get past the Federal Telemarketing law. However my work number is not on the Federal no-call list so they can call it anyway. They did ask if I wanted to refill a particular prescription I have with them.
I started getting calls after I ordered a prescription transfer from Medco and requested the "bill me" option. What is alarming is that they are calling my unlisted number which I never gave them.
I started recieving calls from this number about a week ago. One a day. If I don't answer no message is left and when I do no one is there. If this is from Medco it's just another reason to despise them (they are my prescription provider).
