If this were an honest telemarketer, you wouldn't be receiving the calls as the list applies only to them. Con artists have no regards for the day, time, or any laws or lists. They work around the clock 365 days a year and they're liable to call if they know they'll get any kind of answer from your number. You can frustrate them back if you're able to let your phone ring without any answer at all (automatic included). Do this with unknown callers and watch the amount of worthless calls you get decrease.
