you sound pretty upset and rightly so.
BUT it doesnt seem to make sense. ive never heard of a gaggia like yours or similar arriving in that kind of condition. i would ship it back and demand a replacement or money back.
and yes, unfortunately these things do happen. buying from a site sponsor here means two things:
1. you wont be sold rubbish
2. if by some off chance you are, these guys and gals will take very good care of you to ensure you regain your happiness.
i wonder what your internet vendor will do for you? hopefully it is a good outcome though.
