Just read the following story. A DHL phone scam caused about $9 million dollars stolen from 155 people in Singapore. This is quite disturbding. Not only it’s a lot of money was involved, also because local police received 3,000+ phone calls reporting about this crime, and nothing was able to help the victims.
If somebody comes to https://www.callercenter.com and checked the numbers, it would have reduced the amount of damages. This also shows that in a well educated country in the digital age, there’s still a long way to go for fighting phone scams.
