I work for an investment firm and people call from this number constantly trying to get through to the company President.  They say they are from the US Pensions group and have clients that want to invest with us.  When I try to get additional information. like a call back number or their website, they  either hang up on me, or become rude.  They have gotten through to my boss a couple of times and he's said 'not interested', and I've told them as well, 'we're not interested, remove us from your call list'.  They continue to call!

they called me a mutated freak......
not lying and they knew my name

The reason you are unable to call back is that each of these callers is actually caller from a real number but they are Primus customers, so their real number actually gets re-routed through one of many Primus main numbers.My father has Primus and whenever he calls me the caller ID shows one of the many Primus numbers, usually I get (416) 646-3601, but I have also seen others.So basically if you signed up with Primus today as your phone provider you too could make calls randomly to people and they would get a Primus # on their call display.It is so frustrating and Primus should not be allowed to mask the caller ID number.

They just called me, put me on hold so I hung up, then called back from a blocked number.  Said she was doing a survey for a college project in marketing.  Really looking to see if our company wants to buy promotional products.

This is where the (416) 646-3601 number originates from:

Way Telecom Corporation

I received annoying calls too and just hang ups but eating up my pay-as-you-go funds..

I just got a call from this number and the person was like "HELLO, do you speak Chinese?", no joke.

Needless to say I hung up.

I tried calling it back and it was a dial tone, as though the # didn't exist!
