Ubereats claims I didn't pay

I'm so dissapointed in Uber Eats. Never had an issue like this, but as I see on your site there is a lot of complains about billing.

I ordered kentucky, order number 3F567. I choose the cash option because I had no funds on my card. I was so glad I can pay cash. I got the order, and there was nothing wrong I paid the drive R150, my order R139 so the rest I told the driver is his tip. So I never looked at the app again until Yesterday when I want to order again with red letters that I need to pay R139 before I can order. How is this possible when I paid cash, so I will have to pay double for my order? Pay cash when delivered and again with my card to clear the funds? I contacted uber eats on facebook, and I'm disgusted at their response . This is their one response, below and everyone have the same wording. The last text was the funds on the app was from a previous order. I assume this mean before THIS 3F567 order. How strange, it's the same amount I paid for on the 17th. Here's the response *Thanks for reaching out.

As we're mentioned, your account is currently in arrears from a previous order.

We have cleared your arrears as a sign of goodwill. Please note that this is a one-time exception, and should this happen again, you would need to clear your arrears yourself via credit or debit card.

Appreciate your understanding.* End of response

They cleared the funds as a gesture of good and will not aknowledging I have paid cash. I don't why they not aknowledging my cash payment. So I eat for free and forgot to pay so they doing me a favor which is not the case I made payment when my order was deliver. This is so fustrating. It's my fault that driver didn't pay the money to clear it on app. And my responsibilty to make sure he does? Their after service stinks.
