Worst Experience in Delta

Where do I begin? Well, we had a good first experience with Oasis Windows to get our business. Once they secured our business, everything went downhill fast. The windows never showed up when they said they would and when they did show up they were either broken or incorrectly measured! The first time they came out to install the windows, they didn't have all of them ready and also two were incorrectly measured. The second time, they attempted installation (2 weeks later), the large bay window glass broken on the way while being transported. It took another 2 weeks to make the bay window and then when it was installed, they realized it was incorrectly measured (too small!) but they installed it anyway and have yet to return to replace it --- we are still waiting and it's two months later (photos attached). They also made the bedroom window too large for the frame and they have not come back to replace that one either. During installation, they had no regard for their work area. They were in such a rush that they did not even put tarps below areas that they would be breaking glass on the exterior of home nor did they take any measures to protect the interior of home. They carelessly placed or dropped materials on brand new hardwood floor causing dents plus they scrapped and damaged new baseboards. Their installation workmanship was very poor. They used cheap, improper materials such as the wrong window foam seal which expands (should use non expanding foam) which caused our stucco to crack (photos attached). Our large bay window is too small for the house window frame and we have a significant gap on both sides of the window allowing heated air to escape and very cold air to enter our living room. And Oasis Windows has no urgency or even a plan to come replace the windows they incorrectly measured. Despite numerous calls and messages left with various departments, no one calls us back --- appalling customer service. How can they be allowed to operate this way? One thing they haven't forgotten to do is hassle us for final installation payment despite the work not being finished. We have received two letters and two phone calls despite repeatedly telling them the work has not be completed! And once again, we are now sitting at over two months and STILL WAITING for Oasis Windows to finish their work on our home.
