Harassment and blackmail by fake loan app Cridgo via calls and WhatsApp

I am being harassed by persons claiming to be connected with a loan app called Cridgo. They are repeatedly contacting me and my family members through phone calls and WhatsApp and demanding loan repayment. They have sent repayment links and are using my personal information and documents. They are also threatening to circulate my private and nude photographs if I do not pay. I believe my personal data and photographs are being misused and I fear further harassment and blackmail. I request the Cyber Crime Police to investigate the persons, phone numbers, WhatsApp accounts, loan app and payment links involved and take appropriate legal action. I have screenshots and other evidence of the threats and messages and can provide them when required.
