I received a call from this number! But I didnt reply since it was international calling. Very helpful to read your comments guys..! I was right ..maybe was a spam call.. and thanks to you yes of course it was!!... Be careful no one will ask you your credit num by phone.!! I applied last year for an australian visa.. and payment was bank deposit..!after read lots of information in the aus government webpage and fill many legal documents I did! Even in any serious travel agency they wont call you by phone!
