Russian Dmitry Argarkov received a credit card offer and not agreeing with the terms of the offer, scanned the document, altered the terms, mailed it back to Tinkoff Credit Systems, who obviously didn't read the terms, before signing it and sending Mr. Argarkov his new credit card.
The changes made included a 0 pc interest rate, no fees and no credit limit and 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.
When Tinkoff attempted to close the account due to overdue payments and sued Mr Argakov for 45,000 rubles for fees and charges which were in their original terms, but not the altered terms, they lost!
They lost because they did not read the altered terms before signing the contract and sending Argarkov the credit card.
Furthermore, Argarkov is now suing Tinkoff for 24m rubles for not honoring the contract and breaking the agreement.
