Contact the seller and ask about the possibility of recovering cash a check. Some types of cash registers can print a duplicate receiptand after a certain period of time after the issuance of the original. Perhaps the seller will be able to duplicate the check. The second option is ask the seller a copy of the chequeand made on the copy machine.
If we are talking about restoring a checkand a terminal for receiving payments, try to contact either technical support terminal or to the Bank, maintaining the operation of the terminal. Terminals to receive payments store information on transactions, however, to obtain a duplicate receiptnot so simple. Please contact technical support of the ATM to justify the reason you need to restore the checkand write a statement.
With the same request, you can contact the Bank, however, practice shows that banks are extremely reluctant to consider requests of this kind.
