Very poor service with no support

Uber Eats started off well but of recent their driver are getting worse n worse. 1 month ago, the driver told me he cannot walk, n when I specifically ask to deliver to my door! He cut the call and cancel my order. Today another problem, the another driver pick up my order. They do not check. They dont even have a contact detail where u can call UberEats and get them to sort it out asap!!
