I've talked to them 3 times, asking them to stop calling me and remove my number from their list. They just hang up. The best thing to do, is to file a complaint with the FCC. You can earn $500+ each time they call, if you're on the do-not-call list. Even if you're not on the do-not-call list, if you ask them to stop, and they keep calling, you entitled to $500 from the FCC.
We have received calls on all three of our phones, we have repeatedly ask them to take us off their call list. It is never ending, three four times a day some times as late as 9PM.
