Who called from 2138251150

Got a call from this number. Apparently from the US and I'm in S'pore. Wonder where did they get the idea that I'll buy anything from them??? Talk about cross-border harassment...

Hi, I just got a call from the same person yesterday morning. But I refuse to pick up the phone as I was in a middle of a meeting when it happen.

I ask my lab-partner if he know which country this call  is from and he said that could be from Indonesia.

I am at Singapore and I too keep getting calls from this number, refused to pick it up so far.. wonder where they get my number from ??

How to block these annoying calls??

I also received a call from this number, i have no idea about the caller.

got called from this same number 3 times but I never picked up too. I am from SG
