It is called Citizens United........and if you call and wait for option 3 it says they will put you on the DO NOT CALL list, if you punch in your phone number. I tried it 3 different times and each time they got it wrong. I hung up. They are now on my block call list.
I also waited for the operator and asked to be put on the do not call list. After which the operator was very rude while telling me my number would be added to the do not call list. Once I had heard that my number had been added to the list, I hung up. No need to be harangued by someone I didn't want to talk to in the first place. Hope this solves the daily calls.
