Listen, do yourself a favor, don't even answer these calls, because it just fuels them to call you even more. Rule of thumb for me, is that if I don't recognize the number....I don't answer it....If it's someone who really wants to get a hold of you, they will leave a voice mail. Also, Keep reporting them to the Do Not Call Registry. Unfortunately, it seems I'm doing this nightly, but it really does cut down on the unwanted calls, and it gives the government information about these would be scammers......
I'm on the DNC list, but still get unwanted calls! I don't answer calls from numbers I don't recognize. I don't give out my cell number except for family and friends, so assume this is robo calling
