Received a call from local landline +65 6256 6663 claiming to be from Singtel.
they mentioned that my internet connection is not secure and safe, and want to help me with the issue.

I told the man that i would resolve it with Singtel directly, but he kept making excuses. I knew it was a scam call, told him i knew, to stop scamming people, and that I would report the case to the police and hung up.

No losses were sustained.
