Yes hound them of facebook, look for them on twitter and instagram as well. I hate sellers like this it makes the honest sellers fume!!! Also I think it is very poor of the person you contacted at Ebay not to give you proper help, and you had to post on the forum here for help. That is very poor service from Ebay customer support.
And like every other person who has replied to you, never ever let a seller delay you from opening a dispute, if you have not received the item by 40 days (if it comes from overseas or even domestically, especially if your waiting for a repost) open a dispute case. You then have given the postie or seller more time and remember to raise it to a claim if you still haven't received it by the date paypal has given you.
If you do believe the seller and think it is the Australia Post's issue visit their website and make a complaint to them as well, there is an online form to fill in and they will get back to you.
Personally I think this seller has lied to you. But just never ever let a seller convince you not to protect yourself. If it was me I would of rather refunded you, and if you still wanted to purchase the item through me you would be allowed to do so but that way I can reassure you that have your buyer protection and I am an honest seller and worth your time to deal with.
Good Luck!!!
