SSI just called from a 4th number after I blocked the first 3. I answered. The woman said they were not selling anything and had some political questions. I told her I don't do surveys and to remove my number from their list as I'm blocking the 4th number as soon as I hang up. I doubt they will stop calling.

If you call them back using *67, the message asks you to email them at their opt out address. Don't surrender your email to them too. Just keep ignoring or blocking numbers from SSI or Amagansett NY. Both names have appeared on CID during the dozen calls I've received.
