Chinese loan applications fraud

I have taken a loan from chinese loan apps from 70-100 applications from play store. This applications are not registered with rbi nor nbfc. They give a loan of small amount with higher interest by submitting aadhar card and pan card for 7 days or 15 days. They take all access from our mobile like contacts,email access,gallery,location,and many more. If we unable to pay loan amt for 1 day also They start to give threat,they create whats app group and add our family members and friends Also they defame us by writing chor,fraud in group. They call our relatives,friends and threat them. They are also misusing our aadhar card,pan card,driving license,voting card. So what legal safety can be taken to save from this in future. If they misuse documents then what safety we can take first so that in future if they misuse anything we will get save out of this. Can we write nc to police.
