South Bengal State Transport Corporation [SBSTC] — booking confirmed but missed bus due to deviation of bus route

Sir
I booked a ticket online on 07.11.2017 transection ID JSBI[protected], Seat no 30 of 4 PM bus from Durgapur to karunamoyee for the journey on 08.11.2017.I used to board the bus usually at Panagarh bazar bus stand.I waited till 5PM then called the helpline mobile no of Durgapur SBSTC and they told that the bus was gone through Panagarh bypass due to no entry by police but did not give any alternative arrangement.So I missed the bus due by no fault of mine.
So now I am claiming refund of my booking amount as early possible.
Even in normal day the SBSTC buses (up and down) run by the wish of the driver and conductor while running through the Panagarh bazar or Panagarh bypass.My email id [protected]@gmail.com
