I got a call from this number, and when I answered no one was there.  I answered, HELLO three times, and nothing.  About a minute later though, I got a message on SKYPE that my daughter had tried to call from Germany and I had answered and said HELLO three times but couldn't hear her.I called her back on SKYPE and sure enough it was her that had called.  I assume that the number (604) 855-7584 is a number that routes SKYPE calls.  This could be why you get the long busy signal when you try to call it back, and that no one can trace the number to anyone.  This means that you are either getting a legitimate call from someone you know from SKYPE and it just doesn't connect through to you.It is also true then that if the call connects and someone speaks to you and tries to scam you, that they are using SKYPE to make these types of calls.Hope this explanation helps someone figure out who may be calling.

(604) 855-7584 calls me many many times a day!

I had a charge on my account for KNOBKNOCKERS and the phone number was listed as +1 855-604-2020 and when I tried to call it, the phone line was dead. Anyone else have this problem? They stole $107 from my bank account.

I got a call asking to speak to the owner of this property...I replied they are not available ...who's calling...replied Patrick...he would call back...heavy indian accent..not sounding like a Patrick...hmmmm perhaps a deafening blast to this idiots ear would be suitable....

I received a call from this number on my cell today saying they were calling to welcome me to Fido and that the needed to confirm some info with me.  I called Fido in the evening and this number is not on there list.  Fido tried calling and could not get threw.  The same number called me back in the evening and I argued with the lady on the phone cause she wanted to confirm the type of phone plan I had.  I told her to shove it.

We get calls from this number sometimes as frequently as 5 times a week.  Most of the time there is no answer.  A few times we have spoken to someone who says they are from the cancer society or the firemen's association selling tickets for a magic show.  When we get a person we asked to be taken off their call list.  
We've decided to answer and then hang up as soon as it connects.  Feels rude but this is a real nuisance we are trying to discourage.
