Unsolicited merchandise from overseas sellers (Updated 29th Oct 2pm)

Hi all,

I recently received an unsolicited package addressed to me from an overseas seller.

I believe the seller has messed up with a prior order cancellation and thus still sent the item to me despite the cancelled order and refund. I have advised them in writing to organise to have the item collected from a nominated address within a month so that the item can be returned to them.

However, the seller has requested me to return the item via registered post (they will reimburse me the costs afterwards). As the item in the package contains a lithium ion battery, AusPost did not accept the package. Just wondering if there are other options available and / or whether I should just request the seller to organise the shipping themselves.

PS: they have also offered to sell me the item without any discount, but I no longer have need for the item, which is why I am not inclined to take up that offer.

UPDATED 29th Oct 2pm
After I have reiterated that they would need to collect the item from the nominated address, they are still trying to ask me to return it via AusPost.

Hello,
Glad to know that you received your package. even if it has been cancelled, and the total amount has been refunded to you on 15th October, but our co-worker made a mistake, the phone still arrived to you.
Would you like to pay the money back to us? our co-worker would lose her job if we can't get money back. :(
Special link to pay: (link for payment)
Please ignore the picture of the special link.
Sure, if you don't want that, we may send you return address to send it back, and we'll be in charge of the returning Shipping fee.
Hope you'll be the best model we can learn from. :)
