My elderly mother received a call from this number from a young sounding man who said he was her grandson.  He knew my nephews first and last name.  When asked what his middle name was, he gave my father's name.  I took the phone and asked for a birthdate and received a nasty response and he hung up.  I repeatedly tried calling the number and continued getting busy signals.  When I finally got through, they answered the phone "American Embassy".  When I said they were full of crap, they promptly hung up on me.  I figure he was going to tell her he needed money.  I reported this to the Anti-Fraud Centre of Canada.
