What works best for me since I know there is little hope they will stop calling is to press menu option to speak to a live caller. When get a human, I quickly tell them to "F'off, quit calling me" before they have an opportunity to hang up on me. It doesn't solve anything but somehow makes me feel better.
This company has been calling me for about 2 years
Not diabetic ask them to please stop calling but they continue to call
What a waste of my time and theirs
This is very annoying!
