Uber Eats order never arrived twice

Please don't order from Uber Eats, drivers are extremely rude, ordered Pizza yesterday it was not delivered the driver completed by order . I have tried calling him, he was not answering, sent messages responded on his own time. Fine l was refunded and l have decided to order again this morning same thing happened l called the driver there was no answer, sent messages no answer. I could see him on the app going back and forth. All of a sudden he completed my order. - -
