I get this call several times a week. I've received it dozens of times. Each time I asked to be removed, I get the same call from another method. It may be that sleazy work-at-home losers are buying access to this message, then using their phones to spam for a cut of the profits. In this way, this company can continue to make sure you get this method, because the DNC responsibility is on the part of each loser who is spamming you, so this company can keep harassing you forever.
