Parveen Travels — Changing ladies seats in the midnight in bus without prior intimation

I booked a ticket(seat : 8 ladies)from Chennai to Sirumugai in Semi-sleeper bus #CHEOOTY Bus no: TN21BZ3899 on 28/08/2022. The adjacent is empty and nobody has booked. In the midnight, around 12:10, suddenly the driver came and told me to change my seat as the seat 7 is booked for a male passenger. If I'm not changing the seats, I have no other option but to allow the male passenger to sit next to me. The driver was so rude. When enquired in Parveen Travels office koyambedu branch, they said the seat(7) was not booked and asked me to contact customer service. Nobody picks up the call and the toll-free number disconnects by itself. My whole day is disturbed because of this. Please take necessary action on the driver and their co.
