I get a call from this number 2-3 times per day. If I p/u I here nothing for awhile and then a change in the line I usually just let it ring but it's as annoying. I have no company name.

I keep getting calls from 418-907-5997 have told them numerous times to stop calling me but they still do , don't they get the hint not interested stop calling over and over again I get about 3 calls per day from them

They keep calling, and they say hello and hang up.

Try recording the scumbag next time that happens.  There HAS to be some kind of recourse.  I can't believe that these hosebags can be allowed to harass  people like this!

They are a bunch of A** Holes pick up and hang up this way they get charged for the call they call 10 times I pick up 10 times they get charged 10 times only an idiot will keep calling again and again!

They are calling multiple times a day.
Asked if I want to replace my windows or doors offered 35% discount and free estimate. Told the guy that I have replaced 6 windows lays year and I don't need anything, imediatly asked if I want to replace my doors.
Told the guy to f*** yourself with your door and stop calling me.
This salesman called me back and told me that he will burn my house down and started to swear at my in various language.

We are also getting call after call from this number  but no one is at the other end of the phone; silence  then they hang up.. I texted the number and it went thru but they still call but leave no message on the ans machine. It is annoying to say the least especially when you are expecting a call ,or are far from the phone. I can't understand  how they expect to do business by bugging the hell out of people.

Called 6 times in the last week, dead air, no response... Caller ID "Windw Svc Qc"

They called a few times, then I finally answered.  It is a window & Door company who insisted that I asked for an estimate.  I did not.  Now they call about 6 times a day.

They are a window & door company that calls 4-6 times a day, every day.  I answered for the first time this morning & after informing the guy that I live in a condo and cannot change the doors/windows if I wanted to, he hung up on my without saying another word.  I hope he gets 0 sales.

They've been calling my home 4-6 times per day.  Easter Monday, they called 5 times - all after 12:00pm MST & extending well into the evening (7:21pm).  As other posters said, they are offering windows & vinyl.  For the first time this morning, I answered.  After sharply informing the annoyance (that's the politest insult I can use...rest assured, I have much choicer words for him) that I live in a condo & he must contact my condo management, he hung up on me.  Classy.

This is the worst spam-caller I think that I have ever seen. They call every day. Today I counted 4 times in my caller ID in fairly tight frequency. I have the number blocked and have never answered their call and never will. You would think that they would just give up. These people are filthy scum.

They're all greasy from there

A$$hole that spams about doors and windows. When told to remove from list...he said don't have to.
You cannot call the number back. Some greasy  guy from Quebec.
