Home Depot review: Installation of wrong patio door and blackmailing

I am requesting your support in resolving the issue concerning home depot canada for the poor and wrongful installation of a patio door at my house and home depot refusing to replace the wrong door.
I signed a contract with home depot canada (oakville) to replace the patio door of my house at 5401 glen erin drive, mississauga. Home depot contractor was supposed to complete the installation latest by september 3, 2020. After a delay of about 4-weeks, I called home deport and requested that since home depot is unable to fulfill its obligations, the contract may be cancelled and the advance returned. The lady on the phone told me that she will discuss with her manager and come back in a few days. After a few days, she called to let me know that the delay was due to covid-19 and now the door has arrived, and the installation will be completed on saturday october 10, 2020 (thanksgiving weekend).
On the day of the installation, the installers deliberately removed my door by breaking into pieces and did not bring in the new door till the old door was completely destroyed and removed. When the new door was revealed, I told the installer that this is a wrong door and of wrong size. The installer told me that I have 2 choices, let them install the wrong door or they can leave without installation and leave the wall opening open posing security issues and whole house subject to cold weather. They also suggested that we can discuss the problems with home depot and the contractor office on tuesday after thanksgiving. I tried to call the contractor office and home deport. After several attempts, I managed to contact the home deport doors section where a gentlemen told me that this is between me and the contractor and home depot has nothing to do with this.
As planned by the contractor and home depot, I submitted to the blackmailing and allowed the installer to install the wrong door. The wall cavity at my house is 81-inches and the new door with frame is about 74-inches thus allowing a gap of about 6-inches above which is covered with a flimsy metal sheet from the outside and a thin wood decorated wood inside with no insulation etc. The glass is also the wrong type. This door not only pose a security threat but also loss of heating and cooling is also anticipated.
The complaint was submitted to home deport asking replacement of this door or complete refund so that I can engage a competent contractor to replace this door. A complaint was also filed with bbb. Home depot asked for a copy of agreement and pictures of the door which were provided. On november 2, 2020 an email was received from home depot informing me that this is a correct door and offered $700 for the metal stress and offered to modify the existing door so as to bring it to the door committed this modification will be done by the same blackmailing contractor. I declined this offer and asked for the replacement of the door or full refund. I also told home depot that this blackmailing contractor will never my house again.
On the other hand, home depot informed that the new door is the correct door and a gap of only 2.5 inch exists which is standard (lied since the opening is about 6-inch). Bbb closed this case without informing me. I have requested bbb to open the complaint again.
I have not received any response from bbb and home depot on this subject. It seems home depot has moved on ignoring my complaint. If needed, I shall submit the copies of the contract and the pictures of the door.
