As reported in The Telegraph - when Dmitry Argarkov was sent a letter offering him a credit card, he found the rates not to his liking. But he didn't throw the contract away or shred it. Instead, the 42-year-old from Voronezh, Russia, scanned it into his computer, altered the terms and sent it back to Tinkoff Credit Systems.

Mr Argarkov's version of the contract contained a 0pc interest rate, no fees and no credit limit. Every time the bank failed to comply with the rules, he would fine them 3m rubles (£58,716). If Tinkoff tried to cancel the contract, it would have to pay him 6m rubles.

Tinkoff apparently failed to read the amendments, signed the contract and sent Mr Argakov a credit card.
