No support from customer services for outside the box problems

Kiss your chances of receiving any customer support after 6 months goodbye. If you're purchasing something in advance, DO NOT leave the parcel unopened for longer than 6 months. I bought an office chair in April 2024, just as building renovations began at my office. I didn't want to open the parcel Makro delivered until the renovations were complete, as I didn't want my new chair to get damaged. The renovations were only completed in December 2024, so that's when I finally opened the box. As I began assembling the chair, I realised that important parts of the chair were not included in the box. Without those parts, the chair is completely useless. I immediately contacted Makro to explain my situation and request the missing parts, but all I've received are stock-standard responses telling me to log a return on my profile - even though I've explained at length that the delivery was over 6 months ago, so it's not possible for me to log a return. Offering a solution that doesn't relate to my particular problem just proves that they're not actually listening to me, and any problem outside the box (excuse the pun) cannot be helped.
