[Resolved]  Rio Technology Company — asking money

Gd evng sir.
I applied for part tome jobs in naukri, quiker etc. Then i got a message in whatsapp from rio technology company offering me a part-time job. Then i paid for the 300 as registration fee. Then they asked me to send adhar card details and passport photo, . Later they sent me an agreement in which it is written that if i fail to get the 90% accuracy, i need to pay 10000 to the company as maintenance and utility fee. I agreed to that. Then they send me some agreement software in which i gave my digital signature.. They sent me the agreement along with workload.. I completed it and submitted it back to them. Three days later they sent me a report stating i didnot reached my accuracy.. After 2 days they called me at 11.00am and asked to pay 10000 before 11.30am or else they said me that they will proceed legally by court.. As i agreed to agreement i paid them 10000 from phonepay before 11.30. And asked them to send my payment receipt and also told them to clear my matter. Then they called me and said i need to pay 14500 again to clear the issue.. As it is not mentioned in agreement, i rejected to pay it... Then they called me continuously insisting me to apy the money or else they told me that they will go by court..
Please help me solving this problem as soon as possible as this is not known to my parents. This is the thing many students are facing these days in name of online jobs...
I paid them 10000 as given in agreement.. But i cant pay further.. So please resolve my issue immediately
