I also received this call many months ago but I played along with them because I know they try to scam me because I don't have that much money, debt or anything worth that much. In the end I told them that through all their calls I managed to track each one of them down to their house, cars and etc and in the next 24 hours all the authorities will be looking for them unless they stop this scam and they hang up immediately. The last guy called me said he was a police. I asked for his police number and he refused and started to sound so mad. Then I told him that my dad is a high ranking officer in bukit aman and my mum is deputy attorney general. He hang up immediately too... LOL...
