On April 28, 2024, I traveled from Paris (Bercy Seine) to London (Victoria Coach Station) via a FlixBus service, with a departure time of 10:15 (Paris time) and an arrival time of 18:55 (London time). My booking reference number for this particular trip is 315 443 4163, route 700. Unfortunately, upon my arrival in London, I realized that I had inadvertently left my suitcase in the luggage compartment of the bus. The suitcase in question is a medium-sized black one with four wheels, displaying some minor scratches, and branded "Newcom." Immediately upon recognizing my mistake, I hastened back to the station within a mere 10 minutes, only to find that the bus had already left. Despite my swift actions to retrieve the suitcase, which included visiting the station on the evening of April 28 and again on April 29, as well as lodging a report with FlixBus's lost and found department (report reference number: 37302145), there have been no updates or leads regarding its whereabouts. It has now been more than two weeks since my first contact with the lost and found service. The inability to find my suitcase, which was left in the luggage compartment of your bus, for such an extended period is unacceptable. This lack of professionalism on your part is simply unacceptable. I vividly remember the driver who operated the route and have provided all relevant details. Despite suggesting the possibility of contacting the bus driver, FlixBus declined to do so, citing privacy concerns. While I acknowledge my own error in leaving the suitcase behind, I am profoundly dissatisfied with FlixBus's approach to resolving this matter. I believe the company's actions—or lack thereof—could be construed as negligence. Consequently, I am considering taking legal action to address this situation.
