I also received a call from this number, and it was a voice I couldn't recognize, and then it hung up.  Doing some research, I have also read comments that it ended up being a person's mom (above) and another saying it was an uncle calling from the middle east.  

This implies to me that this is an outdial number for a discount long distance brokerage, and it's being reported as (416) 555-7777.

It would be interesting if someone, who actually recognizes / knows the caller, were to ask which long distance company / discount company that they made the call via.

The scammers that are calling are probably using the same long distance discount company to place their scam calls.

automatated phone call saying my debit card had had a security bleak and I needed to file a complaint immediately with them.  It then asked for my 16 digit debit card number.  I put in all 0's but it wouldn't let me any further.  I decided to hang up at that point and look it up on the computer.

There was no answer when i answered the phone.. i am not outting my name cause i dont want whoever is doing this to know it.. this is bs..

I just received the call from (416) 555-7777 but I didn't answer and no one left a message. I will see if they call back, and, if so, give them a piece of my mind.

Are they just scammers or what?

On my display, it showed sialk.ca

these people (sounded like there was more than one) called me and just said "hello" over and over again. i think i heard laughing in the background too... tried calling it back "the number you have called is no longer in service".all i wanna know is how the hell they got my cell phone number
