APTDC — Wrong bus and wrong seat allocation

We have booked AC sleeper bus from APTDC for Bangalore to Tirupati, and after waiting soo long we got another poor quality bus with stinking smell and we have booked rare seats because my parents are travelling with us, but we got last seat. This is very much unexpected. We have paid a huge amount and was expected a neat and clean luxury bus.
Very unsatisfying experience with APTDC.
Please provide compensation and refund otherwise we have to take another action .
We have booked AC NEUGO HYBRID
ELITE.
Actually we need full refund from APTDC.
We dnt have other option so we have to travel with that poor unhygienic bus 2163.

After booking sleeper bus we are not able to sleep properly.

Take action please
