Indian Army — Fraud of 1500rs for ordering my product

I'm a reseller and he gave a order of 1500. At the time of payment he uses the excuse of merchant card which he gets from Fauji. He stated that he'll get 25% cashback and so he is using that also there is no other way to use transaction facilities as it is a military camp. Please provide justice for me. I'm a student and was starting my side hustle 🥺. Many more scams have happened with me previously of a huge amount. He took almost 3 hours to convince me for each and every thing. He was giving me excuses for not cancelling the order 😕. Please help 🙏😭 Atlast I showed him trust because he showed me his I'd of a sepoy and informed me that he is from Indian army. Please catch that gang at any cost. Collect all the evidences from the people and catch. Such a shame if you can't catch such a illiterate guy. Afterwards I realised how much illiterate he was.
