Grrrr, so irritated with John Lewis

Ordered a dress the other day - it was too big, so sent it back.
Went to order the smaller size, out of stock.
Left email address for ‘email me when back in stock’ - they emailed yesterday pm, I only just saw it, went to order - out of stock again - in every size but size 20!

And having trawled through every single other dress they have online, there’s nothing else I’d even think about ordering at all - at least not unless I was 37 and a size 10 again.
