Remember that it takes time for money to be transferred to the University's account. During this time penalty might be increased as it grows with time according to the contract.
In this case provide the evidence of payment for penalty to Sechenov MFC. Your debt will be reconsidered according to the date of payment.
Please note that in case of having an agreement with a company, the evidence of payment is company-to-University receipt and not student-to-company one.
