I lost an expensive tablet computer inside a bag with my school ID. I don't know the company, as the taxi cab we got into was from the airport and was not label (as far as I can remember) well. I've tried calling the Objects de Troves number from the US (821 00 25 25) but can't get through. I'm not sure if I'm dialling incorrectly or if they don't accept calls from the states. What should I do?
