Travolook — Booking cancelled but amount not refunded.

I tried to book a flight ticket from Hyderabad to Thiruvananthapuram on travolook.in on Feb 2nd 2022. The transaction of ₹4903.00 was completed,
Then I get a call and mail from tavolook customer service that the ticket PNR was not generated due to a technical issue from there side for which the transaction has been cancelled with reference no. REF[protected] and I will be getting my refund of ₹4903.00 in 7-10 Business days.

I have been writing 6 mails talking to travolook customer care but didn't get any prompt response. They just keep giving new 7-10 Business days I ask them for a confirmation mail they just disconnect the call.Its already more then month but still I didn't get any resolution.
