I received the same calls. Luckily did some research & bumped into the posts here by the forumers. In the end, play airplane with the scammer, said kena contact B Covid-19 & can't attend last minute, need to self quarantine. Maybe next time only lar (give face to nicely turned them away but they pretend dumb & asked when will my quarantine be over, niamah betul).

They are very persistance. You blocked the numbers already, they will use another number, keep on blocking, they will use other number & new name. Guess during covid-19, scammer also susah cari makan, lol.

Thinking of it, you won't know there will be any MK profited from the investment 6~7 years down the road. Better invest in something you have control over it.
