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

Same here...got a call from (416) 504-6641 and right after another call from unknown number....

Call from 845 263 1532 saying they know I have problems with Windows.  I do have a problem but not actually with Windows.  I hung up and they called again straight after.

Looking for owner info.

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

I Got a call from (416) 504-6641. She said she is from Microsoft Service center and received an error notice from my computer. She asked me to go near the computer and tell her the license #.I knew it is scam. When I ask her to give me her phone # so I can call her back she gave me (845)263-1532. She is from India, I don't bother call her back.
