It seems that you have been a victim of a scam call that is pretending to be from Delhi police and asking for money to remove your name from a case involving a call girl. This is a common fraud technique that is used to extort money from innocent people by creating fear and panic. You are not alone in this, as many other people have reported similar scam calls on the internet.
The first thing you should do is to stop sending any money to these scammers and block their numbers. Do not share any personal or financial information with them, such as your Aadhaar card, PAN card, ATM card, bank account details, OTP, etc. These scammers may use this information to steal your money or identity.
The second thing you should do is to report this incident to the cyber cell of Delhi police. You can file an online complaint on their website or call their helpline number 155260. You can also visit their office at 6th Floor, C-Block, Vikas Bhawan, I.P. Estate, New Delhi-110002. You should provide them with the details of the scam calls, such as the phone numbers, names, dates, times, amounts, etc. You should also keep the records of the chat with the call girl and the scam calls as evidence.
The third thing you should do is to seek legal advice from a lawyer who specializes in cyber crime cases to protect your rights and interests.
