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 it will be regretted forever!
Crooks and Idiots who think they are smart. They want your credit card number to charge you for "service". I'm reporting them to the FBI, BECAUSE I'M TRYING REAL HARD NOT TO RIDE THE FIRST FLIGHT TO MIAMI, fl TO GIVE THEM A TASTE FROM MY GUN
Wasn't home when they called my landline, but am always suspicious whenever I get calls from an unknown source. Have had fake IRS agents calling me, their number has been out of area. So beware.
