VRL Travels — Cannot modify ticket

Address:

1/102, Divya Kiran Apts,, 1st Main Gopalpura,, Santhekatte

I had booked a ticket for my sister for travel to Udupi from Mumbai on 23rd Feb 2023, she wanted to prepone the visit to 16th Feb 2023 because of some commitment. I called VRL office customer care and even sent emails but they said that modification is not possible. Eventually my sister could not travel on 23rd Feb 2023 and hence lost the ticket fare of Rs.982/-
The amount is not that big but its a matter of principle, I am a regular traveller with VRL and did not expect such a behavior
