These people don't give it up, they're relentless! I've told them several times that I'm not interested in getting newspapers. That doesn't stop them. They call asking the same questions about the newspaper.
My advice is to get a call block app on your smartphone and dial *67 on your landline. Otherwise they'll keep calling non stop!
I have asked 20+ times to be removed from their call list...yet they STILL call me, many times a day...almost everyday. I have blocked each number they call from. But I believe that since they're a telemarketing company they have multiple lines. At this point its harassment like. I have gone as far as looking up the number &calling back to ask for my name to be removed...its absurd.
Obviously they are goi9ng to ignore you. Which is why you need to send them a certified, return receipt letter telling them to remove your number from both their internal and external call lists. Also tell them you want the written copy of their DNC policy that they are required to furnish by law. Then if they call again, sue them.
