Dear @Asha_Prasad
To request a refund for the extra ₹200 you paid after changing your bus timing, please contact the bus service’s customer support directly via their helpline or official website. Make sure to provide your booking ID, payment receipt, and updated ticket details. If you do not receive a timely response, you can escalate the issue by filing a complaint on a consumer grievance portal like the National Consumer Helpline (NCH).
Could you also please share the name of the service provider to guide you better?
If still need help, reply to us.
