Kpn Travels — refund or alternate tickets

Hi team,
We booked tickets bangalore to karur. Pick up point at madivala. They asked to come at different location which is not actual pickup point.. Due to that incorrect address we missed bus..

Later we visited to kpn travel office in madival. They assured that will reduce your ticket amount in next bus. But now they said to book tickets that to after 3hr.

Is this good way to treat the customer??
They why you pepole gave assurance??
Instead of waiting i can get some other bus right??
So you please waste my money and time too??
