Who called from 6260025717

criminal just called.....do not answer

They called again.   Asshats.

multiple calls...caller leaves no message

Caller ID window said: NAME NOT FOUND.

When I answered there was no one there so I hung up.

Try this Doctor.
I agree that blocking full numbers does not "work."  The criminals can change one numeral and
a simple "call blocker" will not stop the call.
But if you purchase a device that can block entire area codes...now you are talking!!!   Not literally!
We use and highly recommend the Di*it**e Call Blocker.  The wonderful thing about the Di*it**e is that you can block entire area codes.  Currently, we are receiving calls from distant area codes located in bizarre parts of the USA.
Not to worry, we have over 240 area codes blocked and OUR PHONES DO NOT RING - NOT EVEN ONCE.
Check on Amazon for blocking devices.  And yes, it does make us happy every time a CRIMINAL telemarketer calls and is blocked.
