Spice Jet Airlines — Arm twisting technique of Spicejet for charging higher fares from customers

My PNR number is F61BFL, I had booked my tickets for November 19th 02:15 HRS flight from Dubai to Mumbai. I booked this flight as I had an medical appointment with a Doctor in Mumbai at 11 AM. And also it is my Mothers 75th Birthday so wanted to give her a surprise. Now they rescheduled this flight to Nov 19 23:40. Which totally defeats both my purposes of Doctors appointment as well as my Mothers birthday. When I rescheduled my Flight to November 18 23:40 flight for me and my Wife I was charged a fare difference of INR 14, 960. Calling their call center numbers is like waiting for 35-50 minutes on an International call. Their chat bot or whatsapp bot is useless as they do not have any option to connect with a human agents. My point here is that when Airline has rescheduled their flight then why should I be charged the fare difference. I seek refund of the fare difference charged to me.
