Andhra Pradesh State Road Transport Corporation [Apsrtc] — Delayed arrival by 2 hours connected train missed

I have booked bus ticket from Kadapa to Bengaluru while booking it was shown that departure time at Kadapa is 10:30am and arrival time at Bengaluru majestic is 05:00pm. By keeping in mind I have train at 06:50pm at ksr Bengaluru railway station. So I have booked ticket by having a margin time of 1 hour 50 minutes. Where as the bus started at Kadapa bus stand is at 10:50am and arrived Bengaluru majestic bus stand at 07:02pm. Due to this I have missed my train and I have rebooked bus ticket from Bengaluru to manipal and I have faced so much problems which you can't imagine and it costs me heavily.

Train ticket cost: Rs.1625.75/-
Bus ticket cost: Rs.880/-
I have faced so much mental pressure during the last two hours of journey.
Kindly take action against them and issue refund amount which costs me during the journey.
