Credit Muga — Loan

I had received a message in my WhatsApp that I have to pay, 3000. I was not aware of this I dint get any message or call regarding this loan. So he shared the link to open the app and it was showing i have to pay 3000. So i checked my account statement did any amount got credited to my account and it was showing 1600 got credited. But he asked me to pay 3000 so that i refused to pay. Later he shared nude pics and started blackmailing me that he will attach my photo id and phone number to that and share it to my contact list. So i paid 3000. Now it's showing i have to pay 6000 but i haven't applied for a loan. Please do the needful ASAP if not again these people start blackmailing
