How do we stop unwanted calls?

This party keeps calling my number without permission.  This is an un-neccessary annoyance!!!

Not interested.  Stop calling

They are calling threatening me and calling me at work

I want the calls to STOP!!

I see they called me back in February...no message, hung up on machine, hopefully blocked this time.

I get calls from this number several times a week - sometimes several times a day.

Called today, no msg eft. Now blocked.

they tried again
now they are completely blocked
