Terrible service

I ordered an item on 25/11/2023 and when opening the box, I found that some parts where not in the box. I spent the next few days running around to different hardwares and plumbing shops, but none of them had the part. I called and emailed Leroy Merlin multiple times and almost two months later, I still don't know whether I will be sent the missing parts or sent a replacement or be given a refund.
