WARNING--BEWARE!! These callers are B I G credit card criminals, known as the card service scammers! Under NO circumstances, give these lowlifes your credit card number, or you will regret it forever!
I just got two calls from this number on my cell phone. They left no message. I tried to call them back from my land line. No answer. So I blocked them from my cell line. Easy to do. Bring up number and touch info or the "i" .. then scroll down and press the "block this caller"
