item split in transit, poorly repackaged and arrived damaged

[ghostrider73]

I bought 2 comic books on eBay but when the parcel arrived it only contained 1 book and it appeared to have been tampered with. After this a new parcel tracking was generated with the other book tagged to it. It arrived about 5 days after the first and was repackaged without the protective packaging of the original and arrived damaged. Presumably this was customs or similar. But the question is, who do I go to for recompense? I don't want to return the item as the damage isn't major and its a book I'd been looking for for a long time. In my view whoever repackaged it should pay compensation for damage, but what's ebay's answer?

If it was through Aust Post you take it too the Post Office and lodge a damaged parcel claim and send it off It can take time and they may say it was not adequately packed but then it was by them so point that out.

There sorting machines do chew a few items occasionally and have seen many items with what looks like rubber marks from the  conveyor wheels.
