I've worked a few shifts with this outfit and they seem on the level.  We're just trying to make a living folks, terribly sorry if we take up a minute of your time.  This isn't a scam.

This company is pretending they work with Teresan. I'm a building manager in North Van. They are aggresive and very dodgy.

You can add (778) 565-4499 to the list of phone numbers from these guys.
They just called with the old "Im in the area" etc

I took down the name etc and said I might call them later then I checked right away on Google and found this thread.

Got this call about 5pm on Monday June 6.  This guy told me that he needed to schedule an appointment with me to assess our home appliances since it's overdue.  I wondered if this call was a scam since I didn't purchase any extra warranty on our appliances (and our appliances are all over 6 years old).  I asked him for a number to call back since I was too busy to speak with him further, but he couldn't answer me, then told me there was no number he could give me.

This company has been phoning us for almost 4 yrs  repeatedly!! A few months ago I finally told them to please stop calling. They phoned last week and again today. When I told her this is harassment she argued with me and insisted I had asked for them to call me back. NOT! This girl was so rude , she even called back just to hang up on me. They use different numbers to harass people (778) 565-1036 and (778) 565-1392 the name PGHS comes up on the phone. Dont pick up your phone when they call. They have over 20 complaints lodged against them  by BBB.
