I received a call on 2 dec 2019 at 10.38am. This guy claimed he is from singtel technical department. He claimed that my internet line was hooked up by many illegal users and wanted me to on my computer n he will show me. at first i thought it's might be true as I just fixed up my new recontract router one day before. Then I realised that my ISP is not Singtel and the caller ID showed his number as handphone which is unusual for a customer service officer. I quickly cut my line and call singtel to verify. Singtel said probably a scam. By the way, the scammer sound like an indian. I call police hotline and he refer me to scam alert phone number.
