Uber eats double charged me over the last 4 months

Uber eat app : they charged be double for my purchases 1 when i order and when u tip the driver they charged u again for the initial amount plus tip i thought it was my imagination last month then again today and took my screen shots.I went it to my account and searched for uber eats then realized it happened 4 times to me. But today i took the screen shots ...imagine how much people this is happening to. I will be fighting for my refund and will not be using this application again.
