Travolook — Refund yet to be credited

Address: Gurugram

Website: travolook.in

I booked a flight from Bangalore to Durgapur on 30th Sept, 2021. They cancelled the ticket from their end and said it was due to operational reasons. They also said it will be refunded within 7-10 days. It has almost been a month but my money isn't credited yet. There's no response in mails. And when I'm calling them, they're giving excuse of bank issues. Please help
