Uber complaint: without know complain suspend my app

I worked uber since 3 years and working with good rating and nice comments from customers. suddenly uber suspense my app which I can not login. It happens while I am working time at city which means I already given my 9 hrs time on that day but suddenly on working time where I am away from my house more than 1 hr engaged my time working with uber.
This is not way without any reason to suspend to my app can not login . They send me text message to my help app saying you have a complain from customer but not written properly who is customer and what happen with customer without any reason and time of trip concerns. I request on email please provide which trip with customer i did wrong ? But uber still don’t want to tell what type of complain and who complain about . if I know I can tell truth what happen exactly? That day when I worked on this Saturday, I didn’t do any wrong . There is nothing happen? If I wrong , uber should give me notified and warning while working time then i can contact them but they did unnoticed block my app while on working time around 1:00 pm at city area where I am working? Actually they did unethical and monopoly what they want ? They treat like salvage. we are not salvage what they want . This is totally in behaviour manner policy to the driver without any reason and investigation to believe customers complain. I request before please provide us camera for reason to make proof what happen ? But they don’t want because hiring too many and uncountable driver so they don’t care to driver even drivers are full time or not . And please check commission policy how much they are taking from customers and drivers ? This is time to investigate uber company policy?
