Call to my cell number was dumped by installed app (Mr. Number) because the caller is not on my contact list. After reading comments I realize I didn't miss anything important.
Called my cell, didn't recognize #, didn't answer. If they call back, I'll block the #. If it's important or legit, would have left a voicemail in my option.
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!
