when hell freezes over

a wonderful breezy, sunny day that makes you want to sort things!
so it's time to tackle my worst purchase EVER - a freezer that ices up.
In my own defence, it was an emergency purchase as the old one broke down and we had to replace it a.s.a.p. to save what food we could, and this was the only one they had in the shop but it is CRAP!
