An Endless Pit of Helplessness

I registered with Uber Eats and have yet to make my first order. When I tried to log in I forgot my password and requested the password reset. It asked for an email address associated with the account. I gave all my emails a go and none were recognised. I tried looking through the "help" section of the site and was given NO HELP what-so-ever. There are no call centres to speak to actual people. If you want to ask a question it directs you to the "Guide to Uber Eats" pages and such that don't provide specific help. I can't even delete my account or re-register with my phone number as it show's it as being already registered. It's an endless, helpless, loop. Mr Delivery is just the same. It's completely disconnected. There are no call centre's for customers to contact. I GIVE UP!
