These scamsters operate from out of India. Polic are looking for them to approach them. They will not approach police coz, they will be immediately arrested. Just block them and ignore their calls. All inform bank and all those concern not transfer any money using your pan.

No need to bow down to pressure tactics 

2) refuse to make any payments 

3) police would not intervene 

They would not get your residential address 

You have not committed any offence hence there is no necessity for the police to be behind you.

These people run rackets to extort money from innocent client by exploiting their weaknesses. 

There is no necessity for your fear or worries in this regard.

They may try to mount pressure on you by calling from different numbers telling that police will come and arrest you etc., you don't get scared by their threats, if they feel that they cannot extract any money from you even by their such strategies, they will just ignore it and they may look for another innocent victim.

So, just don't attend calls from any new numbers and do not release the blocked numbers and remain calm over such threats without giving any concern to them, you can overcome them in a day or two.

No, it may not be possible for them to trace your home address by your phone number alone, even if they locate your home you may not entertain anyone and send them away by making them outside the house and if necessary call the police by dialing No. 100 for the offences of nuisance created by them. 

You might have given them your number by some source, if you had transferred the money through UPI then certainly your phone number will be available in the records, hence that will be sufficient for those clever and criminally motivated culprits. 

1) they must be in league with service provider or some on from Police 

Be bold. Ignore her calls. On what ground police can arrest you?.  Take the help of an Advocate. Perhaps from UPI transactions they would have found out your number.

Do not worry. This was a trap and since you was not entrapped they are trying to threaten you.

No one will come to arrest you. However it is better if you inform the local Cyber Police on this asap.

You are welcome Sir. I don't think police is involved in your case. Cyber Police are supposed to keep your Identity hidden.

..

Your identity would not be kept hidden 

It is not illegal 

you mere chatted with her did not have any sex with her 

It was suggested for your safety to approach police with a complaint about this extortion racket by fraudsters. 

If you are reluctant about it then you will keep worrying about it without any relief for your worries.

The cyber crime police will not divulge the details of the complainant during their investigation or after that also.

No doubt the said chat messages are not illegal but you always should exercise caution especially while dealing with such girls through chat messages or any other social media service  because they are documentary evidences which may be used against you in case of any litigation or a criminal action by police 

Chatting with the girl consensually does not invite any offence, as you had not sent any bad photos or videos.  It's good that you deleted all the chats with her.  Be bold. These are all the tricks to extract money from you exploiting your honour.

1. You have not yet committed any crime. So, relax.

2. Now she will arrange a fake call from a person posing as DIG or officer from Crime Branch for which you should not worry at all.

3. Immediately lodge a police complaint mentioning all the phone numbers from where you had received the extortion calls.

4. After few days, send copy of the said police complaint to the local S.P. of Police seeking protection from those people.

1. They can get your phone number  from your PAN Card, UPI transaction, Aadhar Card also.

2. Act as advised in my earlier post and do not get tensed at all. They are trying to extort money from you by black mailing you which you shall have to resist.

1. They are in this extortion profession having developed expertise in this field.

2. So, do not get surprised if you find that they have already collected the address of your house and also your names and addresses of your near and dears for black mailing you telling that they will inform all of them about your seeking the Escort Service from them.

1. Lodging police complaint might help you.

2. Do not entertain them in any way in future.

3. Cyber Police certainly is expected to keep the entire matter including your identity as secret.

1. No. Enquiring about their services like Sex, Massage, Kissing, etc. is not at all considered as an offence as per Indian Law.

2. Relax.

- Since, you have not taken any services then you are not bound to pay any amount to the said escort service provider. 

- Further, your narration is showing that you are in trap of a fake person , and that person is blackmailing you on the ground of correspondence done by you.

- You can lodge a complaint/information with police for extortion under section 384 of IPC, and for threatening to implicate in false cases.

- Just avoid to reply and answer for long time , they cannot take any legal action against you. 

- As per the Supreme Court, & Karnataka High Court, there is no law that prohibits massage by persons of the opposite sex.
