I received a call at 12.07pm from mobile number 81355594. The caller knows my last name and asked if i understand mandarin. i replied yes, and the caller started conversing with me in mandarin. the caller said he’s calling on behalf of MOH and that my tracetogether app will be terminated at 2pm today. i will be denied access to any public areas from 2pm onwards. I did not respond after that and ended the call.
