person calling but not saying anything

These crooks call me 2-3 times a day trying to sell their debt solutions. Well, in the message they left today, they claim to be the IRS. This number is in NOT associated with the IRS! It's based in Seattle Washington. These are CROOKS and MUST BE STOPPED!!!!!! Unsuspecting people will give them their SSN and get royally screwed!!!

I receive calls from this number several times a day. I answered once to just say "Stop calling me" but every other time I ignore. The daily call volume from this number, however, is getting out of control.

I have received this call, when I picked phone no one answered. In the background the noise was like call centers.

I have received a call from this number every hour for the last 24 hrs. This is not a working number if you call it back.

Person actually answered asking for someone at this address who has his own phone number would not leave a message.

Apparently it's a telemarketing/survey company in Quebec called Klien Tel. They've called me 4 times in the past 2 days, however I'm always at work. The other reports I've read have said numerous things.. they other try to sell you something, or just breathe and hang up as soon as the call is answered. I am getting -VERY- fucking annoyed.
