Dear customer!
Your payment has not been made. Try to repeat the payment.
If the error comes from the payment terminal, which is unlikely, we will do everything necessary to correct the error in the minimum time. However, this error is most often due to unforeseen restrictions of payment terminals between countries. In any case do not be upset. There are many payment forms. You can always buy the desired book online at the Publisher’s Book Service.
You can contact the Book Service of Éditions Temps & Périodes for all questions regarding payments, refunds and purchases, delivery and quality of service.
With best wishes!
Éditions Temps & Périodes
