South Bengal State Transport Corporation [SBSTC] — Bus was cancelled

I purchased 3 tickets on 02/09/2023 via SBSTC App of 04/09/2023 Garia Digha (5.40 AM) route which was reserved upto Contai. Ticket No P[protected]. Total fare was 414. But for an unknowing reason the bus got cancelled and we were not informed by the authority. Then we visited Garia Depot and we have to travel by 6.30 AM bus by paying another 414.
We need full refund of money with proper action.
