Theft at Delhi airport

So yesterday (12/02/25) I was at the Encalm lounge at the Delhi Airport terminal 3 between 2am and 5.30am. Someone stole approximately 2100 Dirhams (approx 50k rupees) from my bag while I went to get some food in the lounge. I had kept the money in a pocket in my bag which wasn't clearly visible so I took some minor precautions and since this has never happened before I never thought to take more precautions(I get the part where I should have been more careful). Now I suspect that the passenger seated next to me in the lounge had something to do with this. I knew there was a CCTV camera looking over where I sat. How do I contact the lounge? And get them to check the CCTV footage? I have emailed the airport, contacted a few numbers through the Delhi airport website but no one is picking up the calls or responding to the mail.
