So, an update. Finally heard back from Customer care... Only to be told that they have shipped me an Aura HD by accident, not the new Aura 6". They apologised, told me to refuse delivery of the HD and that once they receive the HD back, they will send me the the correct Aura. Not too impressed.
They did, by way of an apology, provide me with a one time use 100% discount code to use on their site. I guess that's something at least.
