You know What? I will never answer their calls. My process center is Victoria, I live Victoria They can call us there to come for the interview or They can email. If They try to reject My visa because I didn't answer the phone, there is always a way to sue them. First of all, I mentioned in My application The department is to contact me via Any email.. What the hell They call with "no caller id"? They can call as much as They want.. it is weird.. Even in those scams warnings" don't give personal information " What if They have your application number and They make you believe it is immigration.FYI : people call immigrants like us who are on the edge pretending to be immigration and ask forbid money. Beware

I only had a call once on Friday then on Monday. Then no other calls.. it might be because I uploaded some more stuff on My immiaccount or it was a scam
