Cyber fraud

I first ordered a phone from USA... They told me that there has been an offer going on... The cost of the phone was 55,000 with discount.... So I agreed and paid them 5000 as down payment.. Then after some time they again asked me to pay 5000 for the courier company... And when the product reaches at Turkey they asked me to pay for custom charges which was worth 30,000INR .. I agreed and paid them and after a day or two they again when the product reaches at Pakistan Karachi they asked me to pay 60,000 and said it was refundable so I paid them with my school scholarship... But after that I haven't received any refund but instead I was asked to pay 1lakh INR cuz the product has been reached in India and I have to pay them 1lakh which is also refundable... They told me that I will get those refund all together... So I managed to pay them 50,000 and one of them told me that he will arrange the rest 50k ... But after giving them my 50k he refuse to give the rest and asked me to pay 20kINR more... I refused and told him to give me my money back but he is totally ignoring it and threatening me also... I have given them total 1.5lakhs which includes my scholarship also... I am just a student and they have scammed me and taken from me everything... I am hereby hoping for justice from your side as soon as possible cuz they are giving me deadline... Currently in Delhi for study purposes but has been stranded due to the virus...
