These SCAMMERS have several numbers that they call from - this is the 2nd call that I received within 20 minutes. BEWARE - rip offs looking to prey on people for FREE MONEY, CREDIT AND WHATEVER ELSE@@
Cardholder Services is a scam. One time I played along and said "Yes, I am interested to lowering my interest rate" up until they asked for my CC info. At that point I said "Shouldn't you already have that" and got cussed out and they hung up on me. :) Another time I answered "Special Agent Ed Jones" and they hung up. :)
