The reimbursement to the consumer of the sums due by the trader, or any other benefit received under the contract, shall be made without undue delay and at the latest within fourteen days from the day on which the trader is informed by the consumer of his decision to exercise his right to have the price reduced or the contract rescinded.
The trader shall reimburse these sums using the same means of payment as the one used by the consumer when concluding the contract, unless the consumer expressly agrees otherwise and in any event at no additional cost.
