These Guys are blackmailing and asking me to pay 2000 per visit

These people are keep on calling as I own them Lakhs of ruppes, and say should pay the EMI due or face the conseqences, I already told them I will pay the penalities, even though they relentlessly keep on calling. This particular guy named as Akash Kapoor unfortunatly his gender is changed to female named sonam Bhise isn't this a fraud
