Uber unautorised bank deductions

I had Uber app on my phone years ago, but I removed after all the bad review I read in the news, and a friend of mine was ****d by the Uber driver likely he is jail now, I never used Uber nor the food delivery service, people complain about Uber unauthorised deduction during a trip, how about unauthorised deduction for nothing, they have my banking details or yours so they can just deduct, very sneaky as well they try to deduct small amount so they hope you don't notice it, likely I have a block for online payments on my account, so be careful there and check your bank account if you have signed up with Uber in the past, I don't know how they are still in business
