Got a call from 1-866-372-3836- x3 in a short period of time. when i called back its an auto recording of a males voice for "Card services" requesting the last 4 digits of my card number, then saying its invalid and requesting all 16 digits. there is no way to get to an operating and not indication of who it is by internet search. therefore, i call bullsh*t! its a scam do not make it this easy for SCAMMERS to get your credit card number!!! jesus they are losing their creativity!
