UberEats

Got a promo for my first order R75 off I wanted to give Uber Eats a try and I placed an order waited 1h30min and they kept extending my delivery time by 15 min I called the restaurant that was doing my order they claimed they can't see it and minutes later my order disappeared. With not a single trace of it left on my order history instead the only order that appeared was one I canceled. I tried to reorder but now my promo code was already used. I didn't receive the food how can they say it's been used. Am so disappointed I think I will stick to Mr D
