I purchased by Dyson G1 and could track the delivery until I was told to contact Australia Post who then told me to contact Dyson.  Now 3 weeks later and Dyson have informed me that the package is now empty when it got to one of the post transit centres and it t will take up to 30 days to work out what has happened to it.  I have been in touch with customer service and keep getting a template email back thanking me for my patience.  Meanwhile I have paid for something that hasn't been delivered - wouldn't you think Dyson would send a replacement now?  Interested in anyone else's experience.
