Despite having weekly or twice weekly calls, even once speaking with a live person by pressing a button and requesting removal from the list, these calls have continued for months.
Unfortunately all any of that does is prove to them your number is live and active.
I would recommend you, and everyone else here to contact this attorney: http://kristensenlaw.com/310-862-0185-robocalls/ about it.
Until then I like to have fun with the live operator. Making up information and most importantly wasting their time. They'll ask you for your phone number, usually so they can google it. Lately I've been giving them the number that calls me. Takes a few minutes before they realize and hang up.
