Vistara — Money debited but ticket not confirmed

On 23rd december 2021, I booked 3 tickets through vistara air website for total amount of Rs 21309 for travel on 25th Dec from chennai to mumbai. The amount was debited from my bank account but I did not receive confirmed ticket. The vistara staff raised a complaint number 7129705 assuring the problem will be resolved. The details regarding the debit was submitted to customer relations Vistara.

As my travel was important through the help of vistara staff i made another fresh booking and fulfilled the travel.

It has been 10 days since the complaint was raised. I have not received any assurance from vistara regarding the complaint. I am really concerned whether the hefty money that I have lost to vistara, will be refunded or not.
