introduced himself as Mike from some finance compay. if you try to call the number back the message is the "number cannot be reached from this service" - I have recieved 5-6 calls in the last few day from this number and very similar numbers - conclusion is they are all scammers

This no. came up as potential fraud, my ph has already blocked this would be incoming call. Hahaha, at least these scammers didn't succeed!
