VRL Travels — Cancellation of ticket

I have travelled from bengaluru to visakapatam tr no i s 8555720 on 13 october after two hours of journey the bus got damaged .the main reason for the damage was the bus was not tested before the start of journey.
I am thinking that vrl travels was playing with people risk.
And the bus reached the destination late by 5 hours so that I lost my interview.
Again I booked a ticket on vrl travels. From visakapatam to bangalore on 18 october tr no8594069 on the date of journey I have a received a message that the scheduled bus was cancelled.and vrl travels didnt provide any alternatives so that I have to book another bus which costed me around 2400'they didnt credited my money immediately.I Have enquired the reason for cancellation of bus an I got the answer was the bus got breakdown .
So I went to vrl travels in bangalore on 22 and asked them to provide another ticket from visakapatam to bangalore on 1 st november against the cancelled ticket .
They gave me a refund but not provide any ticket.
My question is about why will you not provide me another ticket as I suffered two times because of you I dont want refund,
When I talking vrl people in office the spoken in vulgar language(anandrao circle bangalore cabin section)
I think vrl travels main motive was to earn money
They dont bother about customers and their satisfaction.
I am just informing vrl travels that one customer can ruin your reputation in one minute which you have earned in these years.
