Travolook — Refund Not Proceeded

My name is Dhriti from Bangalore . I had booked an air ticket on 14th July 2022 from Bangalore to Varanasi through one Travolook.in which was canceled by them due to a technical issue PNR didn't generate by Airline REF[protected]. I also received a call from them informing me of the same and I was told that my refund will be done in 7 to 10 working days. However, the same has not been done and mostly I tried to connect with customer care more than 25-30 times and they always just give new timeline for refund date.
