poor service and assistance

So there is a unknown order on my uber eats account since last week... I have been contacting the support team via the app an telephonically. They keep closing my chats on the app and when I contact them they keep saying I'm through to the wrong department and they are going to escalate the issue. when I ask them to transfer me through to someone I can speak to all they say is that department does not take calls and we just have to wait for them to respond but all they do is close my chats... very disappointing service
