The callers are the drug-addicted "card services" scammers who pretend to be associated with our credit card companies in an effort to fool us into giving them our credit card numbers so they can rip us off. Beware of these lowlifes, and warn others before they are cheated!
I picked up and asked the rep why they are calling a DNC number, as there is a huge fine for doing so. He said "I guess we want to pay the fine!" Losers.
Called and hung up on third ring. If it was really my credit card issuer calling, they would have left a message and/or called one of our alternate numbers. They must think people are stupid.
