Well if you keep calling these criminals back, you keep CONFIRMING your number is live. And you think you unsubscribed? How do you unsubscribe from something you never subscribed to in the first place.
Help shut these crooks down instead of calling them back. Complain.
These people won't stop calling me. Like every day. I tried opting out but they never take me off their list. Today they said I won a free trip to Mexico. I never entered any contest. SCAM.
