I. – The payer is entitled to reimbursement by his payment service provider of an authorised payment transaction ordered by the payee or by the payer who gives a payment order through the payee, if the authorisation given did not indicate the exact amount of the payment transaction and if the amount of the transaction exceeded the amount that the payer could reasonably have expected taking into account his past spending pattern, the conditions laid down in his framework contract and the circumstances specific to the transaction.
At the request of the payment service provider, the payer shall provide all information relating to the reimbursement requested.
II. – In the event that the amount of the transaction exceeds the amount that the payer could reasonably have expected in accordance with I, the payer may not invoke reasons relating to an exchange transaction if the reference exchange rate agreed with his payment service provider was applied.
III. – The payer shall submit his request for reimbursement before the expiry of a period of eight weeks from the date on which the funds were debited. Within ten working days of receipt of the request for reimbursement, the payment service provider shall either reimburse the full amount of the payment transaction or justify its refusal to reimburse, indicating the possibility of having recourse to the mediation procedure referred to in Article L. 316-1.
IV. – The refund provided for in this section corresponds to the total amount of the payment transaction executed. The value date on which the payer’s payment account is credited shall not be later than the date on which it was debited.
