Be aware of Uber eats

I really feel so disappointed while writing this. I think theres ****s and ******* working for Uber eats, its disgusting!!!!! I placed an order R92,40 total, I paid with my bank card, somehow they only took R84,40, and says I must give the driver the remaining R8. I assumed it was his tip. When he delivered I gave him R10 and he gave me my food. Minutes later he came back telling me I should pay R213, I asked why as I already paid for my food, he just said yeah it’s showing on the App. Mind u its at my workplace, the driver kept interrupting me while i was busy with a customer, insisting I should pay, I showed him my receipt but he kept on, and its not the first time, last time I paid cash and received a message later on that I didn’t pay my order, ILL NEVER ORDERED FROM YOU AGAIN!!!!!
