I do something similar except I give them the phone number of my state senator. I figure if these pricks swamp his lines enough maybe just maybe Congress will do something about it.
"Marilyn" from Cardinal Advisers left message that it was important for me to call her back to discuss all my Medicare options (coming up on 65th birthday). I am sick of these calls. I will already get free medicare advantage program that includes drugs from my retirement package with my employer. Call came from this number but callback number was 919-650-3696. I have reported it also.
