I too have a Prestige PRT 325 FFCS which is just 2 years old and has developed the same problem whereby the freezer has stopped working and the fridge freezes everything. I am amazed that there are so many others with the same problem. I have arranged for an engineer from a local firm to call to look at the freezer but may now cancel that and contact comet first. I am going to register problem on the Watchdog website too. I will ring Comet and will use "the letter" if no joy........
