Travolook — Money Not Refunded and Fraud

I booked a ticket on 28th June 2022 and I received a call from their team saying that the Fare has expired and I need to pay extra or else they would refund my money, so I denied to pay extra and asked for refund and they assured to refund within 7-10 days and its been 1 month and no refund yet and moreover the fare was same on the website for next few days. So its clearly a matter of FRAUD.
