Yep, same old cardmember/cardholder services scam.  I just wasted 28 minutes of their time with bogus information.  Here’s a great way to waste as much of their time while minimizing the time you waste with these criminals:
* First a little homework.  Look up any 2 credit card company’s first 4 credit card digits and customer service 800 numbers (there’s a list on wikipedia).  Make up the rest of the information.  It helps to write it down for use later.  Also be prepared with a fake name, fake billing zip code, and fake last 4 digits of your SS number.
* When they call, be receptive to their offer.  Make sure the amount of debt  and interest rate you tell them you have satisfies their requirements (about $5000 over 2 cards, 19% interest usually works).
* Supply the info for a bogus card.  They will go away to “verify”.  When they come back and say it doesn’t work, re-supply the same credit card number with 2 numbers switched (but not the first set of 4 numbers).  When they come back again unable to verify the card, have them try the second bogus card, and repeat the whole process.
* At this point it has probably been 25-30 minutes.  Sometimes they just disconnect, sometimes they ask to call you back (I give them the bogus number they called me on), or sometimes this is an opportunity to get into a swearing match with them.

unwanted call even though i signed up for the protection

These people keep calling so have a little fun... when the ask u a question come back with something ramdom.. like Beans make me fart, i like broccoli ,  I hate cookie Monster, or just keep repeating " What what I cant hear u can u Hear Me???" Mom is that u??? Is everything ok? Whats wrong with dad..  Damn phone.. and kind yell.. But sound concered. and hang up..

Yep, I've done the same thing several times.  Here's what else I do.  I tell them that I am at work in my office and they've called me on my cell phone.  I don't want to use up my minutes, so could you please call me back on my office phone and I can provide all the information you need.  They say no problem.  I then give them either the phone number for my local Federal Trade Commission office, or my nearest FBI office.  Let them get the same nuisance calls as the rest of us.
