Uber Black drivers are not completing pickups

So I have been trying to use Uber Black for my daily commute. Rides get accepted almost instantly but drivers are usually far away depending on your location.

After accepting, the drivers are roaming around all over the city doing God knows what?

They'll not respond to calls, neither the messages.

So my question is - who owns those cabs? My guess is these drivers are just on salary and do not get any compensation from ride fare. They might be on payroll of a company which owns all the cabs.

Has anyone else faced this in Bengaluru?
