Double charges and Uber closed complaint without investigating

Dear Uber Support, I am writing to dispute a charge that has been incorrectly app**** to my account. The trip in question was paid in cash directly to the driver at the time of service, yet I have received a notification claiming that I still owe payment. Please investigate and rectify this error. Kindly confirm the trip details and payment method recorded by the driver. I would appreciate a prompt resolution and removal of the outstanding charge from my account. Thank you for your attention to this matter.
