Time to shut up shop

As a follow up to my INR case post of a few days ago I've decided to shut my shop for a while.

I'm getting requests every day now for items not received (dating back to mid-August onwards). Many were smaller things sent as large letters (so no recourse there). Other things I did not add tracking within the time frame allotted, to be protected by seller protection (my fault I know).

Australia Post have failed, eBay don't care. Buyers are impatient and have no empathy.

I can't even bulk edit my listings to express post upgrades or registered letters as so many of my older listings don't have the (ridiculous) required item specifics. 

It's just easier to have a holiday & let the complaints roll in and refund as they do (and not create any more headaches that I already have).
