I had received phone calls from some unknown man asking me whether I need a loan . Calls were made from private numbers . Yesterday was the most recent one .

I just received few minutes ago from 6517-2616 voice message about DHL changi airport regarding package for me . 

Editor's note: Scammers are using spoofing technology to create fake numbers, hence, most of the numbers shown on recipients' Caller ID are fake. Do not entertain such phone calls but simply hang up when you receive one.
