received a call on March 5, 2020 on my mobile from +65 3737 8744. a man with a very heavy indian accent called claiming to be from Singtel. It sounded like he was in a call centre. He said he had information that my internet line had been slow in the past couple of weeks. I told him that was not the case. He insisted I go to the router and check something. I asked him if he was taking me for a fool and at that point he started insulting me. Various heavy slurs which I will not put in writing. He then hung up.
