I have been receiving many impersonation phone calls. The calls started off with robocalls and attempted to impersonate various Ministries. For one, an "automated call" from High court of Singapore saying its my final chance to clear my summons and i need to press a number to talk to a officer. Phone number used: +6562564158

One more kind that is quite regular is from "ministry of health", saying my citizenship will be revoked (i am a permanent resident) if i dont press 9 to talk to an agent. phone number used:+6589496489

Look out for calls with the + prefix and if possible, don't pick them up.
