Who called from 2143052151

Tell us more about this "call blocker".  Is it for landlines?  Where can I buy one?  DNC list isn't working!

Calls every day. I've already blocked 4 or 5 numbers from American Heart Assoc. but they just use other numbers and the calls keep coming.

Called landline 11:30 am Nov. 17. No message was left. Hung up on answering machine

Called today at 8:20.  Did not leave message.  We know no one in Texas.  Did not answer.

Too many unwanted calls which are bothersome especially when old and unhealthy. I will not answer a call that I do not recognize. W hen will they give up?
