No.
No idea. That is something to dig later. When dealing with such issues, it is important to deal with one (issue / query) at a time. For now, I am waiting for the next letter.
Also it is easy for them to answer this question or put the blame on another technical glitch.
From what I remember, I had ckyc-verified account earlier. When I installed the app sometime last month, it asked me to initiate vKYC that I simply ignored and then uninstalled the app.
The online cyber crime complaint was forwarded to my district headquarters and there was a call to me if I wanted to proceed further. I asked them to close as it isn't a fraud by the user. So, the complaint is closed.
