My kids were talking on the phone with their mother's and by checking the number it was (416) 210-3998... Try to call back but a recording told me that this number did not even exist...

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

I just found out that this is a place called "Season"s House", an affordable houseing project in Quesnel, B.C. Apparently there was a person staying there from Ontario, and the shelter is now looking into the situation, there may have been phoney phone cards sold to some of the residents there. Will keep this site posted, my son is going to be calling me from there tonight.

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!!

Ok I just called it back n it aid its not in service. When I call a pay phone back, which I tried, it says this number does not receive incoming calls. ok im freaked out kind of cuz why on earth is some freaky dude calling n hes calling you guys to??? im so tripped out right now...
