Guy from India called, although caller ID said it was from Virginia. He said they'd lower my credit card interest to zero because I had such a good payment history.
I gave him a made-up credit card number I previouysly validated as phony at http://www.validcreditcardnumber.com/ and he checked it. When he said it was no good, I told him it worked fine at the gas station the other day.
After a while I told him my next-door neighbor was from India. He finally realized I was jacking him around and hung up.
