Repair wardrobe door, blind and towel rail

I need help with three small repairs as soon as possible. One wardrobe door does not close completely; the exact cause is unclear, although the door appears slightly misaligned in the photos. The roller shutter blind still moves but does not stay in position, so it may need repair or replacement of a suitable part. I also need the bathroom towel rail replaced or reinstalled. The photos show a metal rail and existing mounting hardware, with fixing points visible in the tiled wall. Please assess the fittings and bring or supply compatible replacement parts if needed. The work is indoors and involves checking the existing hardware before making the repairs.
