UberEats expects me to pay twice for one meal

I ordered food that came to a total of R186. When the driver Tinashe arrived I paid him R200 cash.

Now Uber is telling me account is in arrears and I have to pay the outstanding before I can use the app again. After multiple emails explaining that I have paid in cash and I cannot be held liable for something that is the drivers fault UberEats still refuses to clear my account stating that there's nothing they can do and I will just have to pay AGAIN.

This is unacceptable to say the least
