Non-Refund of ₹900 Paid for Bus Ticket Date Change After Cancellation of Bus

I booked 3 bus tickets for 9th November through AbhiBus. Later, I personally contacted Raj Kalpana Travels Pvt. Ltd. and paid an additional ₹900 to change the journey date from 9th November to 8th November due to my travel requirements during the Diwali festival. However, the bus scheduled for 8th November was cancelled by the bus operator. I received a full refund for my original booking amount through AbhiBus, but Raj Kalpana Travels Pvt. Ltd. has not refunded the additional ₹900 that I personally paid for changing the travel date. Since the bus operator cancelled the service, I should not be made to bear any financial loss for a service that was never provided. Despite the cancellation, my additional ₹900 remains unrefunded. I consider this an unfair business practice and deficiency in service. I request the company to refund the full additional amount of ₹900 paid for the date change, along with appropriate action to ensure that such practices are not repeated.
