Got a call today, don't know where it is nor who is calling, I have quit answering any of these unknown calls.  Please tell me there is something to get rid of this nuisance kind of calling.  I get more than a dozen sometimes in one day.

Hello Hello Hello
I don't get that many but my solution to this mad house of robo calls the @$$hole student loans and extended car warranties is to look in sites like this to see what I can find out about the number Then I make the number a contact member of my DNA calls listing (Do Not Answer). Then give the groups a silent ring tone and a silent notification sound. It works great. I don't know when they call unless I happen to have the phone in my hand at the time they call. They can disturbed me the first time and that's all. I usually don't put over 25 to 30 numbers on each DNA list. Then I go to DNA1 then DNA2 and so on. I am on my second go round thru the alphabet. DNA1A  DNA1B That's how many numbers I have blocked this way. Does the job and I don't have to download another app to do it.
Good luck stopping them.
The Do Not Call list is basically a joke.
Have a great day
