The site looks very genuine, though there is no phone number. I ordered a pair of ugg boots and paid. The money has been taken out of my account by 'ugg store'. The boots have not arrived.
I have emailed twice in the past two days, but when I re start my computer, the copy of the mail I sent has mysteriously disappeared. So I assume ugg store sent a virus of some kind, with their confirmation email.
I have filled in the email form on their website, hoping for a response.
If nothing turns up in a few days, I will get a refund from my bank and the site will be reported and closed down eventually. I will not be shopping on line for the foreseeable future.
