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!
Received a call from this number, but didn't answer. I typed the number in google and this post came up. I have downloaded Call Blocker Free - Blacklist on my last two phones and it works well. You do have to actually enter the offeding number into the blacklist the first time. After that you don't hear from them again!
