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

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.

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.

hundreds of call no one on line .is getting to PO me.  Yes

According to my phone's log, I missed an incoming call from (416) 279-1365 at 13:48 on 2012.05.29.  This was the only call in the log around that time.  My voicemail received a message from this number at this time on this date.  It was a message from Yak's customer service in response to a request I made.  I am a Yak customer.According to other comments posted here, some "pay your bill" calls came from this number.  If they owed money to Yak, then these calls were legitimate.  I always pay in advance, so I've never received one of those calls.

This number is for Yak Communications. They are a telephone and, as of somewhat recently, an internet service provider. They are based primarily in the US but have been  branching out to other countries over the lase year our so. I live in Canada and my roommates and i have an account with them. We haven't missed payment on a bill, but they still call constantly. sometimes, there is someone on the other end, asking for my roommate (when he calls them back with the toll free number they give me, the say we are late on our payment, which we never are) but most of the time there's just a few seconds of silence after I answer than then a click like they hung up. I don't know why there are so many people also getting hang up calls who are not with Yak. If anyone can shed some more light on this, it would be much appreciated.
