Oval Solutions — fraud

I had been searching for part time jobs on quikr and this company (Oval solutions) rang up and said that they will pay me 13000 if i will be able to complete 10000 captchas in 7 days if they're 90% correct and if i failed i will have to pay 5000 i agreed and they made me signed a contract just by asking otp they had send me on my e-mail and after searching about this company i came to know that it was fraud so i dropped the work and now after around 2-3months they are again calling claiming to speak from delhi high court and to pay either 2 lacs or 5000. They're continuously calling and messaging me to pay and torturing me mentally..
