We too have received a number of these calls.  I am not returning any of them - just letting them ring through.

APR 2009-- re: (416) 210-3998 .This may/may not be a calling card and it is DEFINATELY/confirmed that it IS some weird MAN (in his 20's-30's) who is like....totally creepy. May be at cell # (403) 801-5295 ALSO, calls from both #'s within moments.BEWARE!!!! Report all harassment!!!

Its a Calling Card NUmber!! Stop freaking out!

I just had the same number call my phone twice but I didn't answer because I was on another call. When I called back I got the message " A person using a pre-paid calling card has tried to call you, please hang up now".

this number has called me like 7 times in a row now. I'm ignoring it. AND my bf picked it up like a week ago n same thing. some guy called to talk to me...

I had a call from (416) 310-3998 but i was busy so i didnt talk to anyone...then when i tried to call back it said that the number doesnt exist...thats weird!!
