They never leave a message but continue to call even on Saturday. I refuse to answer I'll report them to the Do Not Call authorities. You can also call the number back. You get a recording to take you off their calling list by pressing #1

It's a company calling in verify that someone iat this number has diabetes.  I told them it was none of their damn business and asked who wanted to know.  The caller hung up.

caller ID said SDG- no message left

Ive been called many times and they just hang up
