Travel Triangle — Delay in refund and unprofessional behavior of staff

I had enquired on 4N/5D package to Hongkong. While initial conversation was good, the concerned person (Mr. Piyush) showed completely different attitude once the advance money was paid. When i intended to move away to another travels for the same tour, he came back offering discounted price. I had made choice and moved to another professionally managed travels and have fully booked the tour

From March 01, 2024, i have been following up on mails for refund of my amount. He said deduction of INR 2000/- as convenience fee (for zero convenience provided). Even INR 900/- which was due for refund hasnt been paid till date.
