I have a Firenzi fridge/freezer, the brand which does not exit. It is in need of defrosting frequently and the back of the fridge gets a layer of ice on the back. The freezer section frosts up fairly quickly. I am sure it just needs a spare part or cleaning. I live in London SE3 M: 07977 129144 E: post@whimsters.co.uk Please contact if you can fix it.
