The do not call registry can take up to 90 days to start. Also remember once you’re on it, if you do business with a company they can call you again UNLESS you specifically ask them not to.
What happens is this.
I deal with Bank of American, tell them put me on the “Do Not Call List.” They comply.
Then I do business with them and the “Do Not Call,” is an “OPT OUT” list. So somewhere in my dealings in small print, it’ll give them permission to call you again. So they do and you have to ask them all over, “do not call.”
I know I had my account at one bank and Chase bought it out. So because that bank was on the list but not Chase, when Chase bought it, they were now conducting business with me and they could call me again. So I told them “Do Not Call.” And they complied.
I noticed more and more companies get around this by making you sit through an advertising spiel before they’ll connect you to a live person to help you with your question
