Keep receiving calls from this number. I will not pick-up. They will not leave a message. Is there anything I can do to block this number?

I too keep getting calls both at home and on my cell.  No message.

An foreigner with an Indian accent calling from a Medical Clearing house with information that I had Bladder Sling surgery. I hung up.

I would like to know where these off-shore people are getting my medical information from and who they are getting it from. It is illegal for anyone to give out my medical information per OSHA. I will find out who these people are and will report them to the state government offices. I have their phone number. they call me at least once and sometimes twice a week. I keep telling them not to call me and they keep calling me back and when I ask them where they got my medical information from they hang up.

you can block.  On Iphone edit their number and scroll down to where it says delete number.. Not sure on other cell phones
