File a fraud alert with the credit reporting agencies and also get your credit card number changed. I think these people are credit card thieves. Since they can spoof your phone number, they can call your credit card provider and make it look like the call is coming from your phone. I think all they need is the last four digits of your credit card to access your account. That is one racket, asking for your card number is another. If you reported your card stolen, they should not be able to do anything with it and hopefully they will get caught when they try to buy something with it.
My new approach is to pretend interest and, when they ask for my credit card information, tell them I have to go find the credit card. Then I let them sit and wait while I work on the computer or do something else. In a couple of cases (after they've waited several minutes) I tell them I am on the Do Not Call list and never had any interest in their so-called service.
I got a call from this number. Thinking that it was related to one of my credit cards, I pressed 1. When I asked which credit card it was for, the agent told me it was for all credit cards... this got testy and when I answered that I pay my credit cards on time, the agent hung up one me.
Yes these people break the law with their calls to # on the "Do not call lists"
And farther more do it with a recording ! I hate having to hang up on a recording without the opertunity to tell the caller how I feel about them calling my number illegally!
