Uber eats *******

I have had a few problems with Uber and Uber eats and I have decided to complain to somebody other than Uber as they do not respond at all. On 2 seperate occasions, I have ordered Uber eats and I have paid in full, only to be reported for not paying in full or for not paying at all. I have also been overcharged as a result of my Uber getting lost. I have reported the issues, only to be told that I complain too often. This is unacceptable. I don't know how to escelate this further as Uber is very difficult to get hold of
