866-558-6855

This number has called me about a dozen times, sometimes twice a day
and never leaves a message except for a 3 second blank msg

Called me twice today - with just a hang up mesage. ALso when you call it back it first just 'hangs'...no ringing, no answering, no nothing for about 20 seconds...and then becomes a very fast 'busy' signal.

Weird, baffling and really annoying!

Hello, got a call today from an "Irene" from "World Wildlife Organization" from this number. Asked for a specific member of the family-was not home and so she hung up. Wouldn't worry too much, probably just telemarketer calls for WWO.

This number calls my home office 3-5 times a week with nothing but empty air. When I call them, the line just picks up and hangs, just like CentralOntarioGal's comment.

I'm a night shift worker, so the multiple calls a day (some days up to 5) are super frustrating. I have to leave my ringers on because I'm also "on call" while sleeping :(
Just like everyone else, when I call back, there's nothing - no ringing, no nothing.

I get a call from these guys about once or twice a day. Don't know why. No one on the other end of the line. F***ING annoying

I have the same annoying call from this number.. Have any of you done an IQ test online where the results were text messaged back to you? There is a chance this number is linked to that, but not sure..?????

Called me about 8 times in the last three days. Same as the rest

These are the culprits:

4 or 5 calls a day. Annoying as hell.
Report this ph No. to Canadian Marketing Association.

World Wildlife "Federation" is the legit org.

My cellphone started receiving numerous calls every day from this phone number after I made several donations to charities over the Christmastime.  Suffice to say, I'm going to punish those Toronto based charities for the next several years and only give my money to International charities or just forget about "helping" these "non-for-profits" whose Managers still make way more money than me in the FIRST place!

World Wildlife "Fund" is the legitimate organization.

they call everyday during my lunch break, but I never answer it. I hate telemarketers and just don't have the time for them.

Calls me at least twice a week for 3 weeks now. No answer and I wont call them back.

Call me few times everyday.
sometime i picked up and they said nth.
today, finally they speak up and they are from WWF, world wildlife fund or sth like that. I have been donating some money every month. can't believe they are begging money in this very annoying way.

Same thing happened to me... I got fed up and finally after more than a month of their calls three times a week or more I answered my phone and just pressed "0" and "*" on my phone a bunch until I finally got a voice on the other end. They asked for me by name and all that and I asked to be put on the Do not Call list. I'm not very confrontational, so I think I did it somewhat politely but I was pretty mad. I hope it's over. If this is their way of collecting money for a charity it’s extremely flawed.

They have called my wife's cell, my house, and my cell. No-one answers when we pick up. What good is an organization that doesn't complete it's calls? Useless!

It is a toll free line... how about we get back at these A55#0!35 and keep calling them back, toll free for us, but they pay for the call, and leave so many messages that their answering line fills up....

When you call it back it says it is echo marketing... sounds like a scam to me...

God is it ever annoying Every day for the past month, 1 to 3 times a day I get these idiots calling, but there is never anyone on the other end...  If this is WWF who hired these cornholes I am about to pull my support to them.

Someone keeps harassing me every single day sometimes multiple times and it is sooooooooooooooooooooooooooooooooooooooooooo ANNOYING!!!!

I answer but no one says anyting even after saying hello many times.... it has been going on for weeks now.

It had better not be WWF or I will stop supporting them, they already beg me by postam mail and email to give more and I already do it every month... if they can afford telemarketers to harass me, then they can do without my support, I can find more deserving charities.
