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 answered hello and they said "Hello, this is heather with account services-" and then the call cut out. No company name was stated. Obvious ploy to get me to call back and pay for a expensive call. Scam.
