Query: Disappointment

I was very disappointed to realise on receiving my Breville electric wok that I could not use it in the UK because it works on american voltage which is incompatible with the UK electrics. Consequently I now have a very nice brand new electric wok that I cannot use.I feel that there should be a warning about this in the information about the wok on the Amazon website.
