intergraded fridge?

i have a necht intergraded fridge and the hinge is brokrn which means the door wont stay closed. Can you supply me with spare hinges and if not do you know where i can get them. I have been asking the kitchen company that i bought it from and they keep on telling me they are out of stock and this as been going on for 6 weeks now. So i have a brand new kitchen but are unable to use my fridge.I would really appreciate if you can help me in this matter.

Kind Regards
