Who calls from this number, who? When you call back there is a dial tone.

I received a call from (604) 678-5888 from someone who sounded like a Chinese guy I could tell from his accent, told me he was a windows maintenance contact ,asked for me by my full name and asked if that was me, when I replied yes, he put the phone down immediately. I tried to call the number back straight away it was a dead number, how is that possible. I tried it several times, I am now worried in case somebody hacks into my system.

This number has called previously and also tried to have my husband give them access to his computer, info etc. Yesterday they called again and ever since we have not been able to use our phone as it says "line in use"  I can hear static on the line but nothing else

They call me at 903am today. But didn't pick up!

SCAM!! With the sound of a busy call center in the background, a polite sounding man began the call by telling me that they have detected a "problem with your Windows PC". When I asked what the "problem" was he said his company had received a report that my computer has been infected.  This idiotic scam struck me as so funny that I burst into gales of laughter and when I stopped for a breath, the man said, "Don't laugh like that, Madam. You'll get a heart attack", which made me laugh again. I asked him how he could do this (scam) and sleep at night, he sputtered a little, but when I asked him how he could look in his children's eyes, he hung up. Following this call, I tried looking up this number but - surprise - it can't be found.

ya i got that number (604) 678-5888 earlier today and they said they had my license of my computer, so i replied " well what is my license? and they and i exchanged a couple of words. well heck i was actually busy cooking ! and now i burnt my dinner.  so these people have too stop!

They are from the "Windows Service Center" and they have "detected" errors on your computer....Hmmmmm....Could they really be who they say they are?
