Problems with integrated Ocean fridge freezer

I wonder if anybody can help? I let my flat out in the UK (live in France) and the built in fridge freezer is on the fritz. Not worth repairing and I know that they don't make this particular model any more. Would anybody know where I can get the exact same size/equivalent model to fit into the existing housing? There are two doors in the housing, one for the upper fridge the lower to access the freezer. The dimensions are

Height: 156 cm
Width: 54 cm
Depth: 50 cm

Its manufactured by Ocean but don't know where they are as it was part of a built in kitchen from MFI.

Many thanks for any advice

What is the fault with the fridge freezer ? if looking for new one fridgemaster,bosch and beko do them sizes

Thanks for the reply! Its basically defrosting on its own and is not instead of cold....

Sorry Tonto33 just checked those 3 manufacturers and can't see anything 156CM high? Any idea who manufacture 'Ocean' brand? Cheers for the help
