Sometimes you've just gotta wonder about how this person managed to apply for a Credit card in the first place...

There's a charge on my credit card bill I want to dispute. I've already paid it.
Do you have your receipt for the other payment?
Of course I do!
OK, what form of payment did you use?
I gave them my credit card.

And then what?? You thought Friendly Credit Company was handing out free money on the day you sent in your application? Who in the hell doesn't know that when you make a charge you eventually get a bill for it?

Someone, obviously.
