VRL Logistics / VRL Group — the bus journey on 1/03/2018 from manipal to bangalore

Address: Bangalore, Karnataka, 560079

I had booked a semisleeper ac coach from manipal but later due to delay the bus couldn't make it and i was changed to a non ac sleeper coach. And in the middle of the journey there was a problem with the bus. We were changed to government ksrtc bus and were supposed to pay extra for our travelling. I either need a proper explanation or a refund of the extra expenses.
