A company should never ask you to verify such broad information, for example want kind of credit card you have, your interest rates, where you work, etc. If you question me, call your bank and listen to the kinds of security questions they ask.
When you challenge the existence of "credit card services" they get really upset. However their is no website or email for them. I was told I can not be taken you off of their call list. I asked to speak to a supervisor, the supervisor told me his first name was"supervisor", last name "manager" and then giggled....
I got a call from this number but didn't answer and of course leave no msg. I called the number back and said number has been disconnected or no longer in service. Glad I checked here to find its a scam!
