Mkting call campaign -- completely annoying

No one responded when I answered

They have called my house probably 5 or more times. The first couple times, I was able to press a number and get to representative where I asked them to take my number off their list. They just hung up on me without responding. Lately, they are hanging up when I answer or before I even answer. SO annoying! It shows up Olympia on my Caller ID

Call but left no message at 8:39 a.m. in the morning.  Bunch of annoying cowards.  Will call my  telephone company if calls from this and other numbers can be blocked.  Does anyone know if we can report it to a consumer group of federal government group.

My Panasonic phone (KX-TG 6441) has the ability to block numbers when phone service has caller ID feature. I just place the unwanted harrasssing number in the CALL BLOCK list on my phone. When the call comes in and is identified, the phone sends a busy signal and hangs up. The number shows on my list of calls received but a circle x shows the call was blocked, so I get the satisfaction of knowing that I am back in control of my own phone!
