If your Colissimo tracking indicates that your package has been delivered, it means that it has been delivered. If it's not directly in your mailbox or in person, it was dropped off at your dressing room/caretaker or at a neighbor's while you were away. Only La Poste can provide you with information by calling 3631. You can file a complaint/complaint with them if your package has really not been delivered. If your package has not been left at your dressing room/caretaker or at a neighbor and La Poste confirms that your package has been delivered, it is possible that your package has been stolen directly from your mailbox. In this case, you will have to go to a police station to declare a theft from a mailbox. Our team undertakes to send you a brand new package free of charge provided: - Whether you have opted for the Secure Delivery (Loss/Breakage/Theft), or the Fast & Secure Delivery - Whether you have a loss of parcel confirmation certificate issued by La Poste, or a declaration of theft issued by your police station.
