Software Update Scam ,  Impersonation Scam

While using my computer, I received a message purportedly from "Microsoft Support" ). Subsequently, at 11:22 AM, I dialed 64334317 from my mobile phone. A person named Michael, who claimed to be a Microsoft staff member, informed me that my computer had been hacked. He proceeded to share my computer screen and offered to assist me in filing a report with the Singapore Police (SP). Feeling uneasy about the situation, I decided to contact 999 using my wife's phone. Upon learning that I was speaking to the SP, Michael abruptly ended the call on my phone at 11:55 AM. Following the advice of the SP, I reached out to 1800 7226688 and NCPC. Later, at 12:13 PM, I called 64334317 again, and a lady with a child's voice in the background answered the call. I would like to share this encounter to warn the public on this Tech Support scam.
