Receipt of suspicious call stating misuse of my personal information by cyber criminals and alleged cyber crime FIR against me

My name is Shounab Dutta, a PSU employee, currently based in Chennai. On date, I received a call from an anonymous no. An automated message informed me of a cybercrime reported against my name in Hyderabad, warning of potential criminal proceedings if I didn’t act. I was connected to a service executive who claimed an FIR (he shared some FIR details) was filed against me for alleged identity misuse involving MDMA, human trafficking, and weapon sales. I was instructed to write a specific statement and then redirected to someone posing as a Cybercrime Police Department official who asked several questions. I was told to report to the Hyderabad Cybercrime Police station within 2 hours, which I couldn’t due to my location. Instead, I agreed to give a statement online via Skype or WhatsApp video call. I was given the WhatsApp number [deleted] and instructed to send information there before arranging a video call. After sending the information, the call was disconnected. Doubting the legitimacy of the call, I contacted the Cybercrime Toll-Free number 1930, who advised me it was likely a scam. I was instructed to file an online complaint on the National Cybercrime portal. Thereafter, I lodged a complaint on National Cyber crime portal. My question is - Whether there may be any authenticity in the case ? What is the general flow of action which the Cyber department follows in case of a Cyber crime ?
