paid twice

I occasionaly use Uber when i cant use my own vehicle. I used Uber on December 18th 2021 which was a trip that was paid in cash. Fast forward.... i used Uber again in February on the 28th 2022 which was a card payment. I was then suprised to have two debit orders on the same day from Uber.... 1 for the Current trip and 1 for the Cash trip in December last year. I immediatly lodged a claim on the app when this was discovered two days later. Their response after requesting my - Bank statement to proof the debit order - the cash trip receipt which i had to download from the app -A screenshot of the trip of December. RESPONSE " THIS TRIP TOOK PLACE MORE THAN 30 DAYS AGO AND SHOULD HAVE BEEN REPORTED THEN" So how do i handle this? Ive sent numerous emails which only got the same response. now emails are longer being responded to. How do i get my money back?
