Missing IKEA Grimo Covers & Unresolved Delivery Issue

I am extremely unhappy with IKEA due to the failure to deliver four Grimo Covers that I purchased. The Invoice Document Number is 2212022000004069 and the purchase was made on September 6, 2022. Although the items were mentioned on the invoice, they were not included in the delivery receipt exchanged between IKEA and Borusan Logistics. Here is the invoice and delivery receipt for your reference.

I have been in touch with the officials at the IKEA Bayrampaşa store for around a month, trying to find a solution, but unfortunately, the problem still persists. Even though they admit the delivery was not complete, they haven't provided any proof or made any effort to fix the problem.
