Worst client service you can imagine. I normally do not write feedback - but in case of OPODO I have to in order to prevent others from having same bad experience. We booked flight to and back from US. Due to COVID situation this could not happen. Luckily the flights were changed in schedule, so that we could claim refund. After endless calls with incompetent Helpdesk from OPODO we managed after more then 6 months to get our money. And this was only thanks to the professionalism and flexibility of United, which refunded in spite of not having received a refund claim from OPODO. We had to directly manage this with UNITED, as OPODO was not able to. So tx to UNITED and never again OPODO! Keep away from this company if you do not want to lose a lot of time when something goes wrong!
