[ImprovingLizard]

just come off chat with Asos and I assume it was successful as she asked "For the missing items you would prefer refund or replacement?".
I requested a refund and she then said "I've raised the requested successfully now with the specialist team and you'll get the confirmation email from them."
Just now waiting for an email response but hopefully everything goes great

You should still get it I think. I think it's because you've gone over the £150 limit the rep couldn't give you it on the spot. Usually you will get the refund notification whilst you are still talking to them.
