where can I purchase a lower door hinge for my Necht fridge ??

I have a Necht Fridge...which is the sort with a wooden door which covers the fridge door. Both the hinges keep breaking because of a design fault. Does anyone know where I can buy hinges for Necht fridges? The supplier I purchased the fridge from is virtually impossible to contact...either constantly engaged...or will not answer the phone. I would very much appreciate any help.
