Customers are responsible for selecting their preferred courier service when placing orders. RISIS offers a variety of courier options to accommodate individual preferences and requirements. In the unfortunate event of a lost parcel, customers are required to directly contact the designated courier company for assistance. While RISIS is committed to facilitate communication between customers and couriers, it's important to note that the resolution process ultimately rests with the courier service. RISIS is more than willing to relay any messages to the courier company on behalf of our customers. However, please understand that the resolution of any issues lies within the purview of the courier service selected.
