We control everything that happens from the moment you place your order until it is delivered to CorreosExpress (domestic shipments) or UPS (international shipments). Once it is in their hands, in the event of an incident, we must contact them to resolve it. In the event that your order does not arrive, it may be for different reasons. 1. The carrier has tried to deliver it twice and has not located you. In this case, the order will be returned to our offices and you will have to pay the shipping costs again. 2. We have run out of stock, you will receive an email to know how you want to proceed.
