When I recently obtained a new phone number, I wanted to make sure this new phone number would be private. I told the phone company that I want my new number unlisted. They said, “ok”. I said, “I also want it: unregistered; untransfered; unsold; unbought; unmerged; unanalyzed; not improperly stored; concealed; undisclosed; and top secret classified. They assured me they understood. Again I made sure, being polite because I am sure they were exasperated.
My first call on my new private number just minutes after it was set up was… a computerized telemarketer. Someone else had the phone number before. When he had my number, he apparently asked the phone company for extra-listed.
