Travolook — Airline Ticket Refund Amount not Credited

Address:

836, 2nd floor, Udyog Vihar Phase V, Sector 19 Gurugram, Haryana 122008

I had booked two flight tickets in travolook site for traveling from Chandigarh(IXC) to Chennai(MAA) and Chennai(MAA) to Chandigarh(IXC) on 23rd June 2022.
But later I got an email from travolook that your ticket has been cancelled due to PNR not generated by Airlines and your amount will be refunded to your Account in 7 to 10 working days. It's been 45+ days but till now I didn't get the amount.
I called customer care many times, every time they are saying "it is initiated from our end, there is some problem from merchant side and we will initiate it again, you will receive it in 5-7 working days and no need to call back". Please help.
