Please advise, O Mumsnet jury.
I was told that a relative would like a particular Pandora charm as a Christmas present (it wouldn't be my personal choice but I'm happy to go with it as they collect them and it solves a present-buying problem for me).
Said charm however was available online only and not in stores. So I sent off, it arrived quickly.....and was faulty - very obviously missing a chunk of sparkly stuff.
Annoying. Sent it back (it can't be returned to a store, has to go back by courier...to Belgium....) with a note stressing clearly that I want an exchange not a refund.
They did a refund.
Started again, teeth by now very much gritted. Replacement has just arrived and although it's sort of OK-ish, I can see that the outline of the charm (it's an initial) is wobbly and doesn't look perfect. Like a line of solder that's been a bit botched iyswim.
Do I send it back again (having rung them and remonstrated strongly)? Or give up and hope the recipient doesn't notice? TBH if it was me I'd be disappointed but I'm a bit OCD about this sort of thing. Can I be bothered, though? BTW it's the size of a little fingernail and cost £25 plus £5 non-negotiable postage 
Bloody Christmas!
