To get to know the bank details for a refund, you need to contact your bank's support service. Bank details should contain the following information: settlement account number (20 digits), identification code (BIC) of the bank (9 digits), full name of the settlement account holder. In some cases, the requirement of the bank is to specify additional details - bank card number. If you do not have a settlement account in a bank, the refund can be made to the account of your friends or relatives, but only upon a written application signed by the payer.
