Over charged customer

I ordered a meal from Fatboy Burgers, Bromhof, which was delivered on time. The quoted price was R169.67, and I added a tip of R36.77. Then I was billed R 206.67, which was correct. I received two emails from UberEats and decided to check my account. I was billed twice, once for R206.67 and again for R36.77. Talking to them, they confirmed this is correct and that is it. The double-charged me for the Tip, I am very disgusted with their arrogance.
