Ubers refusal to take responsibility for their drivers actions

Very unhelpful customer service. Their business revolves around having no responsibility for their drivers bad behavior. I had a trip with a stop and as soon as I got out the car to collect something at the stop the driver canceled the trip and drove away with all my groceries. Uber said they would not help me or reimburse me and said I must contact law enforcement if I had any items which drivers refuse to give back. It’s scary how this allows drivers to become opportunistic ********* because they know there will be no consequences for their actions.
