This number has called multiple times the last couple of days.  Mostly shows up as 'unknown name', but did come up one time as 'sialk.ca' who appear to be a long distance reseller.

I finally did answer a call since the constant callbacks were annoying.  A woman asked for me by name and told me that Yak Communications asked her to call to give me a special money saving offer.  I cut her off indicating that the phone muber is on the National Do Not Call List, and asked they not call anymore.  Hopefully they will stop calling.

Sick and Tired!
I have been gettting 3 to 4 calls a day from this number. They never leave a message, I am sick of getting these calls. How can I block this number?
I have answered a couple of times and I hang up after he says hello, I can barely understand him because he speaks poor English.

What can a person do?????

I've gotten a few calls from some Indian a**hole (named "Gary" would you believe).  The scam was he wanted to give me a cheap mortgage and all I had to do was give him all my banking info, SIN # and so on.  The first time my wife answered she laughed and told him to suck eggs.  I wasn't as nice.  I'm listed with the CRTC no call list, so I rarely get calls now but this is different...some sort of scammer.  Time to start answering with the air horn again.  Maybe if he's deaf, he won't be able to call cause he can't hear the replies.

Call from (416) 555-7777 (unused number) then hangup.
Caller id was "sialk.ca"

The CRTC will be involved next time.
My number is on the "do not call" list.

this person called me at 5 30 today, didnt leave a message, strange

This is a scam. Do not give any information. Just tell the nice Indian, Pakistanny or whatever or wherever they're from that we love the cow meat they are sending over! Makes great hamburgers!!
