Indian Army — 11,250 paid by me to him google pay

Address:

Hyderabad- Telangana

I run online food services, so he ordered 40 plates for shamshabad airport address for evening . I gave total amount of 4000/- and delivery charges 250/- rupees.
He asked me to put 1 rupee and said u will get return 2 rs, this is how military org works.so first he asked me to put 4200 in his account and said u will get 8500 return.But immediately said some error got stuck ur processing is pending, so I need to put at least 5000/-, but still I was why should we transfer amount to you, but he explaining this code that code, my daughter said we will see, he said your money is with you only I didn't receive, so please do it, otherwise I should show my bill.so again we transferred to him, then he asked how much you have balance you pay me, then I said 2000/-, pay me immediately u will get all the money. we got panic within minutes he confused sending this Qr code that code and we transferred to Najma Begum whose google pay name we transferred.
And finally he was asking us to transfer 8500/- rupees, ask someone your friend and deposit no time, please do it, he was back o[censored]s.
Then we realised what is is trying to do, he pulled all our money to his account and still demanding to deposit more.
Please I agree we made a big blunder/mistake, please help us to get our money.
Thank you.
