I am not blaming Australia Post for the condition of it's RETURN. The buyer opened this dispute. Not me. The buyer claims there was damage when she RECEIVED the item (for which it was insured for full value.)
That's beside the point when there is now a MISSING part.
Thanks for your opinion. I have already reported this to FSO, PayPal, eBay and the Police. I'll leave it the hands of these 'experts'.
