Until the borrower accepts the offer, no payment in any form whatsoever may be made by the lender to or on behalf of the borrower, or by the borrower to the lender, in respect of the transaction in question.
Until such acceptance, the borrower may not, in the same way, make any deposit, subscribe to or endorse any commercial paper, or sign any cheque. If a direct debit authorisation from a bank or post office account is signed by the borrower, its validity and effectiveness are subject to that of the credit agreement.
