Received a call today about 10h00 and yesterday from this number (416) 279-1365). Take the call but no response...

These people originally identified themselves as a duct cleaning company. They call constantly, even though we have told them we are not interested and not to call back.  They do anyway.  I threatened to report them for harassment.  No effect.  It's starting to creep me out.  Now that I realize there are others posted here, I start to wonder what exactly trheir game is.  Is it possible they are trying to determine when someone is home?  Or not?
I have spoken to people on these calls.  Is it possible they are trying to hack into computers through the phone lines?  Who knows, but it has goine way beyond aggravating.

For over a MONTH now this damn number has been calling CONTENTLY like 10 times a day...no ones ever speeking on the other end..we have called it back and it says it doesnt exist. SO annoying... And so retarted!

Yesterday and today my wife receives over 15 calls made within 2 hrs. from this number which is from Yak communication. All calls made with 10 minutes intervals (By law in Ontario no company can make that many calls in one day which it was for the money we owed them for amount of $28.00 which was past due only about 35 days, and in fact I had paid it last week, but they kept disturbing my family at home and Although I also cancelled my account with them last week by emailing them officially and in spite of it they kept bothering my family at home.
I have been using Yak for the last one year and I made long distance calls to overseas every week end, and I always paid these people, but few time they disconnected my call while I was talking to my relative back home, and I had to pay just $12.00 (so called past due amount)just to be able to call back again. I have paid these people over $600.00 always on time but they disrespect me and instead kept emailing me that I owe them money.
If you are askng me about this company I am very upset about them, and I will never use them anymore.

Calls almost everyday...no one ever on the other end.  Very annoying!!!!

They call my place like a million times a day (thankfully we have call id and are rarely home) but they keep asking for some name that i dont understand and then say that i am currently with bell (which im not) but im a renter so i dunno if that affects it, i just hang up on them, they must be selling something

This is Yak Communications... call back and ask to have your number put on their DNC list.
