Contact your phone provider, many will block numbers for you.

Dave,Don't waste your money on a cell phone if you think it'll stop these calls.  I get just as many of these stupid calls on my cell as I do on my land line.  I have a feeling that many of these companies just blind-dial all the numbers (i.e. 0000-9999) in any given prefix they know is associated with a given city, regardless of if it's related to a land line or cell.

I have been getting these calls as well.  I am also on the National Do Not Call List and I have an unlisted number.  We are in Newfoundland and I have had this number call my house on a number of different occasions.  Won't leave a message.  I just refuse to answer this now.  They called at 10:00am on a Saturday morning.

I did a reverse number lookup and of course the company is unknown. However it is a Telus number and I am going to contact them and complain that this customer is harrassing me.  Hope it works.

I've been getting a lot of these (all about interest rate reduction for CC or loans) for the past few weeks. They, of course, have absolutely no authority to negotiate your rates (lender and CC company only do that) .... but I guess these criminals work on the view that you can con none of the people some of the time, some of the people all of the time, and some of the people some of the time. I just block the number but the pests just switch to another number. I had a 978-570-2313 earlier today (now blocked) and voila, just now a call from (403) 255-8807. I may be filling up my call block list .. but listen up you cretins....I'm a persistent little buggger - I can keep up with all the calls you throw at me. P.S. Dave benefit of cell phone is that you can switch it off easier than running around the house after all the land line extensions. P.P.S. don't waste you time changing your phone number, they use random digit dialing and will soon hunt you down again.

Yet another call...when they will get a point!!!
