I am a restaurant Listed on Uber eats

I am a restaurant Listed on Uber eats. For 8 months I have been trying to get my money from them. 8 months ago I changed my banking details. (Change of entity) I was asked to fill in a form and Docusign which I did and I sent them proof of bank account. seven months later they entered my bank account in my Uber eats manager However they still have not paid me. In the mean time my money has disappeared from my Uber Eats Manager and they have still not paid. I have received three phone calls from ladies who can hardly speak English. Questions are never answered by these people who phone me. Now 8 months later I have received another phone call by a lady who cannot speak English saying I need to go through the whole process again which I started 8 months ago. What an Organization They don’t deserve to be I. Business. All the emails I send them are answered by auto responder emails They never answer a question or have a human on the other end. This is very frustrating
