Pella Window & Door Stores

I have a 10 year old Pella large patio door. Our contractor accidentally broke the glass on one side of it. I called Pella to replace it. They sent a service person to the house who looked at the window...measured it...took the serial number of the window and took pictures of it in order to replace it. They told me at the time that the whole door panel including the frame and glass would have to be replaced on that side and that it would cost $2700.00 to do that. It seemed very expensive but I agreed to go ahead.
They said it would ready in 4 weeks. Sometime later I called Pella again to change the lock and check the integral screen as neither were working. They fixed them and charged me 169.00 for the visit.
The screen still does not work.
on the date they set up the delivery guys arrived with the new door and upon inspecting the existing door...said that the new door that they had would not fit in the frame. I told them that the installer that came to measure had taken all the info and that there was no doubt about the age, type of door or the replacement needed. They said that it wouldn't fit and that it would have to be built again.

I called customer service at Pella Canada and talked to Flo. She said that they would put a rush on the replacement as it was Pella's fault that this had happened. She said she hoped it would be about 2 weeks as it was their fault.
I didn't hear back from her for sometime...so I called again and she told me that the first available installation date was November 14, 2017. ...fully 6 weeks longer. I was very angry as we are trying to rent our place out and now can't as the window is broken. We will be losing a month's rent because of their mistake.
I asked to speak with Flos superior and she referred me to Nardina the acting supervisor. I left a detailed message for her and she has not bothered to return my call. Obviously my concerns are unimportant to Pella. They are a big company and don't seem to care what their smaller customers think or what inconvenience is caused to them.
I bought Pella because of their reputation. I was so angry I started looking online at reviews of their service. There are many, many complaints in Canada and even more in the States. Customer service is poor and there is a total lack of interest in their customer's concerns.
I am shocked and disappointed in Pella. I can't believe that a company with their high profile would treat customers with so much disregard. Doesn't make sense to me.
