Will Didi complain that drivers will be retaliated?

I certainly won't retaliate. Let's take a step back and say that even if the driver wants revenge, what will he use to retaliate? During Didi's trip, drivers and passengers contact each other through a virtual number. After the trip, this number will not work, and the driver and passengers will not be able to contact each other. Moreover, Didi's platform has a protection mechanism, and your complaint should be verified, which may not necessarily affect the driver.
