I found a webite called ukwhitegoods, it appears a common fault with mistrals. I have dismantled the back of the freezer compartment and left it to defrost. Will leave it off for a day or so, and try powering it up again. If it still dont work properly, that site seems to suggest that the 2 thermisters on the freezer panel may need replacing, several people there have done this and it worked, it appears it is a job for the competant DIYer (me), as the 2 thermisters simply plug into the back of the freezer and just need cable-ties on them.
Meanwhile, my mum's bought a new f/f.
And i couldnt believe how big the coil area is in the freezer, you'd think it was a big dairy chiller or something with the number of coils! Anyway, its dripping nicely now

Thankfully we have a spare fridge in the shed, but we lost what was left in the freezer. There wasn't much in there though. phew.
That website actually has a 9 page sticky about my particular freezer

just my luck!!!! "the mistral megathread"
