Uber driver refused to return a bag & camera that was left behind!

Uber usually assists with customer queries , SADLY this has not been the case in a recent incident experienced by my family. A gold backpack with a cannon camera was mistakenly left behind. Uber provided the number of the driver WHO showed no interest in trying to find a solution to getting it back & avoided our telephone calls. This makes one question the honestly of this particular driver. The trip occurred in Washington DC however the driver claimes that she's currently in Virginia & unable to return our possessions. Uber states that will TRY & assist in the return on items & a charge of $15 will charged. Instead we were told that it was not Uber's problem ! No assistance by Uber or the driver has been given. Dishonesty all around !
