Missing Components from Delivery

On 09 November 2025, my order (ID: ***) was split between multiple stores for delivery. The Glen Eagles branch delivered my Kenzo Aluminium Glass Sliding Door Ox (1 Slider, 1 Fixed, Bronze, 2400 x 2100 mm). However, the frame, rails, handle, and wheels were not delivered. When I called to enquire, I was told these items were attached to the door. After careful inspection, I confirmed they are not part of the delivered doors. I further visited my local Builders store and was informed these components are shipped as a separate package, as they are too large to be part of the glass panels. They should have been delivered together with the doors. Despite multiple attempts to get clarity from the Glen Eagles branch, I have not received a straight answer. My builder is about to close for the year, and without these parts, my build cannot be completed. This means my house will remain incomplete over Christmas, which is extremely frustrating. This has been an extremely disappointing experience consider that I have had nothing but great service from the other branches.
