Unpaid amount on Uber profile

I took an Uber on 3 September 2022. The trip was R53, I selected the payment option to pay with card. I then realized that my card had expired and paid R70 cash. Because I don’t use Uber often, I didn’t realize that the amount reflects as unpaid on my profile until November. Upon querying the amount and explaining what happened, I was told that a customer has 30 days to dispute a fare. But Uber is still trying to get payment from me 30 days after. I didn’t not receive and communication asking why the amount was unpaid. Not even the driver contacted me about the unpaid amount which is a clear indication that he received his payment. I refuse to pay twice for one trip.
