haha after reading this i wish they call back just so i can mess with him.

You are all wasting your time reporting these credit card scam calls!!!!
They use a service that hides their true phone number showing numbers that you can't even dial out. So you can't block there calls. I've had 1-000-000-000, 1-123-456-7890, and so on all calling about credit cards.
If you report it to the CRTC you are also wasting your time. They told me that it's an out of country call and they can't do anything about it, and told me to just hang up.
What Can You Do????

Call our home in ottawa, wanted to speak to my husband, using his first name as a last name.  When I asked who was calling and what it was about, because my husband was not home, he hung up abruptly.  Called at 5am EST and 5pm est!!

I have fielded numerous calls from this and other such SCAM numbers with similar stories of calls from Banks, cooked-up Lending institutions, etc. As so many of you have noted there is a common thread that it is an obvious phishing scam, and the caller invariably sounds like someone from India.

[Not to get people tangled up in political correctness, et all, I myself was born in India, so I can fully recognize one from "back home" when I hear one.  Therefore, I have no issue with calling a spade a spade.]

Recognizing, that these scammers / telemarketers / crooks at the other end of the line are downright rude, aggressive, scum of the earth ... have one fundamental need -> to make money.

I have given up on all failed attempts to request them, yell or swear at them.  I have instead opted for the approach to frustrate the heck out of them, by extend the call as much as possible by giving them stupid yet leading answers, with the result the call keeps getting extended, without giving them what they want.  Obviously, the caller finally realizes that he is wasting his time.  It boils down to a simple question of Economics, where they are not going to be making any money.

... and BTW, having figured out which part of India they belong to, in parting I ask them to go back to New Delhi, and stop using their fake Christian names.

... just my 2 cents.
