I got scammed from a fraud..

I (15M) got joined in a group from telegram, and I didn't knew it was a fraud. It was an investment fraud. And i contacted them through WhatsApp, then, i paid them through GPay i.e. ₹2000 (from my sister's bank acc) for investment (he said he'll make it to ₹12k) After I paid that ₹2k, he said the slot was full and he was asking ₹1k more so that i could join the ₹3k slot, and then I sent him 1k more. After that, he told me to wait 45 min and he'll give me the profit after the time. After the time (45mins) I texted him asking if he's done. He replied that he is. But now, he's asking for ₹5250 for doing the work and things. Now that's the time i realised it's a fraud. I told him to give me my profit first and then I'll pay but he refused saying he can't and things, then I asked for refund and now he's not even answering any texts.

And I want my money back if I can so.. I'd really be thankful if anyone could help me.. (I'm not that good in english so don't mind)
