I purchased wardrobe doors and a wardrobe kit from B&Q. The kit comprised 2 columns of shelves. One column kit had all the correct parts. The other column kit had a blank shelf which was supposed to have 4 bracket fixings, 20mm dia and to a depth of about 3/4 thickness. I contacted B&Q on 26/6/20, initially by phone. It's all automated, having negotiated the maze of options, got through to the one for live support. Silence for about 1 minute, then the message 'the other party has disconnected' Wasted money trying that a few times, while at the same time submitting online query on their website and emailing. Had an email reply on 5/7/20 apologising and stating replacement is needed, but no details on when or where. Have emailed several times since, but only get automated reply. As at 1/8/20, B&Q still failing miserably and I'm stuck with a blank shelf. Absolutely useless.
