I got a call from both numbers
(416) 504-6641 and (416) 363-5905
Looked them up and found this page. Seems this scam is common. I'll save the numbers in my phone as "scam" and answer my phone identifying myself as a police officer with the fraud squad next time. Bet they don't call after that.

This Scun Bag did the same y calling and waisting time,just told him to go F%@K Himself... Notice you cant call him back,number is spoofed!

3:30 in the morning waking up my kids, @$$hat!

Got a call from (416) 504-6641 saying they wanted to refund me for the $299 I had paid them in 2014. I said, "oh good, can I get your name and number?" Then he said, "get lost" and hung up. I like the idea of identifying the number as scam and then answering "fraud squad" ;)

Got 7 calls starting at 3:01am to 6:21am. I had the ringer off so I didn't notice. How rude of them to call and bother people at that time. Jerks.

11:30 at night received call from the number, pick it up , some one try to send fax to my cellphone, call them back not a chance, Ops they just call again same nipping sound.

This number called me randomly at like 4am but I was asleep and when I called back this morning it was "busy"

Got a call from (416) 504-6641 wants my credit card info gave him my number then wanted exp dt gave him 10/89 he wants valid exp dt advised him to fix his computer as that is a valid exp date and that card expired

Keep getting calls from this number not sure who it is...thanks

Phoney scam something about "my computer' - couldn't really understand the caller but was clearly a boiler room operation

My 70 year old mother just rec'd a call from this number. It was a person with a strong Indian accent. They said they were from Canada Revenue investigating her. Said they needed information or she could go to jail. My mom told them she didn't understand english well and would need a number to have her kids call back. The man on the phone got mad but eventually gave a her this number 903 213 5577.

Harassment phone calls

Got a call from this number, and they asked me who it was? the. They said "you better not hang up on me". Either a scammer, pshycopath or both.

This phone number is actually by Google. How I know? Because I called myself using Google hangout VoIP service and this number came up in caller ID.So, when people are getting this number, it is because scammers are using free Google Hangouts calling to avoid their identity.
