Ixigo — Reschedule request for flight trip not serviced and money deducted

I placed a reschedule request for my flight trip dated 25 Jan and I have made payment. But it seems no action till now.
I raised the request 3 days back when I got WhatsApp message from Ixigo that I can reschedule.
They mentioned that I will be receiving confirmation in 2 hrs. They are not responding and even not confirming if trip is rescheduled successfully.
