We lost 3 bags with our precious dresses and accessories in it and as soon as we came out of car driver started car and didn't even opened trunk of the car we called him too but no luck. We went to uber office and complaied too but no luck as no body wanted to help us and still waiting for response from them but nobody is helping us this is ridiculous as this is not a joke as it was my wedding dress and uber customer service is worst and not at all helping us.
