If this is real, this guy is a total legend (aka conning the banks at their own game)
Bloke amends terms and conditions on credit card offer so that they give him 0% interest and apply heavy fines on the bank if they change the terms or cancel the contract, sends the signed forms back to the bank, they sign them and issue his credit card without checking them. They later scream foul play and a court tells them to do one. Now he's suing them.
If all true, this is totally beautiful.
