There was this person called (number +65 98444297) my wife on 27 March 2021 saying that the call was from Starhub and her phone connection going to be cancelled in 2 hours due to the number was used in china to register for some illegal activity. sadly my wife fell into the trap and continued conversation with the scammer. later the scammer assured my wife that, they already did the necessary and her starthub account will not be cancelled. after more than 30 minutes of conversation, the person told her that she will get a call from another number and answer only to that number. Also told her not to discuss about this to anyone. within a short time, she got a call from +86 2162310110 number and that number claimed her that they were calling from shanghai police department. they also talked to her for a while saying that her number was used for some illegal activity. During this time i noticed that my wife was talking in phone for quite sometime and looked panicky. So I asked her who was that. then the scammer asked her to go to a quiet room so that he can record some details clearly. i intervened at this moment and asked her to hang up the phone immediately. when the scammer heard my voice, he himself hang up the call. Please don't fall into such traps. starthub or other company will not call and cancel any service within such short notice and they will never inform you such matter over phone.
although she talked to them quite sometime, no confidential information had been shared with scammer other than phone number. hopefully everything will be fine
