Travolook — Not Responding on refund amount

I booked a flight ticket from Bangalore to Silchar on 25 Jan 22 for 11 Feb 22.
Under consideration ticket was issued after making the payment.
Phone call came from Travolook saying additional amount of Rs 1150 more to paid as ticket price hiked.
I did not agree hence they issued a cancelled ticket.
Not able to contact their given numbers.
Keep writing to them saying it will take 10 to 15 days .
Today it's 01 month and 07 days past.
Now I don't get mail also from them.
