Fake Loan App scam Limitbee

I recently downloaded limitbee loan app and after logged i provided the my details and money is credited without even my permission 3400 , 3400 for 7 days. on 6th day i received my salary the moment i received my salary in a minute they started calling me and without even 5 minutes I paid 5800, 5800 but even after paying the money that person deleted all the chats and now another person is calling to clear the loan because in the app it's showing loan is pending. They have contact history,sms history WhatsApp numbers are from Pakistan but normal calls are Indian numbers 2 days back they started blackmailing me like sending nude photos to my contacts but they are not sending any photos. Any suggestions or advice please
