Sorry to hear you've been scammed - did you pay via credit or debit card? If so, I would contact your bank - they may be able to help. If purchase was over £100 and made by credit card, you should (I think) be able to get the money back as the cc company are jointly liable for any purchases you make (as far as I know).
Also...agree with Medusa, not having a go but I would rather go barefoot in the middle of winter than wear fake uggs, most of them are made with the fur of racoon dogs which have the most horrific life and death (skinned alive etc)

If you want sheepskin boots cheaper, Celtic Sheepkins are lovely and made in UK I believe?
