On 28.5.2020, I received a phone call from +65 94943939. it played a recorded message claiming that I had an unclaimed package at Changi Airport. I was transferred to an operator claiming to be from DHL at Changi Airport. She asked me for a package tracking number. When I informed her that I don't have a tracking number and they were the ones that called me, she immediately hung up on me. I think It's pretty clear that the callers are targeting DHL customers. Since I haven't used DHL for a while and didn't have a tracking number, the callers were not able to take advantage of the situation. I have read of other similar scams on the scam alert website, some more serious where they transfer you to phone numbers in China claiming to be the Chinese police Force. Please stay alert everyone!
