IKEA Installation Delay and Poor Customer Service

IKEA canceled the project they provided on the day of installation, stating it was not feasible. I am the one suffering from this situation, yet no one has apologized. I had to go to them to redraw the project, and they are still causing issues.
The installation manager, Mr. C**** from Kartal IKEA, has not fulfilled his responsibilities, leaving me in a difficult position. My kitchen, which I waited 1.5 months for, was not installed because they claimed it wouldn't fit. After going to great lengths to accommodate them, I was told to pay for new products that I was not satisfied with. When I went to the returns department, the staff there acted nonchalantly, saying they would wait for returns to come in before addressing my concerns.
A female manager came and told me that if August 20 was the only available date, I should just wait. I am not willing to accept this level of service. I have been patient, but I am now dealing with a mentality that disregards customers. They told me that my request would only be processed if Mr. C**** approved it tomorrow.
I will be filing complaints through all available channels. If the installation team can leave in 15 minutes, and the sales representative does not contact me, then I am left to suffer at their convenience. Is this how IKEA operates? I have waited 1.5 months; if it was not going to work, they should have said so during the initial assessment. This is not a child's game.
I also run a business and do not intend to cause anyone harm. I want my kitchen installation to be completed this week. I have suffered both financially and emotionally, and I request assistance from an authorized person. This situation is a result of your error, and it does not reflect well on your brand.
