Just don't answer your phone it's either a zombie debt they trying to collect are either a loser scammer. Either way if it was important they would leave a message but do like me just get a call blocker and its a done deal the losers will get the hang up dial tone everytime they call me I love to see their faces when this happens ROFL!!! I don't owe anyone anything but that don't stop them from calling if they know you are a real person they will continue to call but never answer they will call for at least 6 months or a year LOL!!! That's a fact no matter if you answer are not and they will call from so many different numbers it's pathetic but all are blocked haa haa haaaa!!! I just have if your not in my contact that call never gets threw on my call blocker I love this app!!!!
