SOTC — Refund of tour upfront payment

I had booked the tour for South America in May2025 through SOTC vide CGS2503098 on 22/03/2025. As usual, the sales person pushed me to do the up-front payment of INR125, 000/-, which was done immediately. Post that on 25/03/2025, he requested me to change the date as there was no other passengers for my travel date. Thereafter, the company cancelled my trip and confirmed that the amount paid will be refunded in 15 days.

When collecting the payment, the company pushes for immediate payments. But when refunding the amount, they take 15 days. Why is that so?

I seek your assistance to get my refund as I need to make the credit card payments.
