fraudulent credit card interest rate

Like "J", these people don't stop calling - if you get to "an agent" they'll want your credit card number. At that point you've got to KNOW it's fraudulent! I've been getting 2-3 calls per week from them for about 2 years now. I've finally decided every time I receive one of their calls, I'll file a new complaint with the Do Not Call registry. As of today, I've only filed 2 but I'll continue doing this. It's about time SOMEBODY does something about these people.
