Order Paid.

I had 2 orders on UberEATS with different restaurants, and I had a balance of R54.50 on Uber Cash. The first order was paid with the balance on Uber Cash and added cash on top of it. The second order was paid in cash and in full, but the driver says that I didn't pay in full and now I have to pay the balance but I paid and this is not the first time it happens
