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!!

I received a call from a guy at this number... He said he was an exotic dancer and that his wife had spoke to me earlier.... (which was not true!)

Hi! I just received a call from this number, and the guy who sounded east indian, asked for me by name but I did not recognize him, so I lied and said I was not home and he asked when I would and I said around 10pm and he said well I really need to speak to her and I will call her then. This is so weird and my instinct tells me this is a scam, if he calls back I will try to get enough information to inform all of you. I will report him if this turns out to be a scam like I suspect.

If it is just a calling card, explain this:-The voicemail it left me (automated voice) : "Your callback number is 4870"and then a text! (From 1-4870)"Please call 4870"

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