Repair to a defy fridge freezer F-660L ALSIL

The fan in the fridge has stopped working and it’s not cooling.
Then i also need some spares, if you send me an email address or whatsapp number i can send you some photographs.
One glass freezer shelf.
One “vent” for the bottom of the fridge.

Am also having issues with the water and ice
– water in the ice tray is not freezing
– the water that’s supposed to come out the dispenser only works for a couple of hours after the fridge has been defrosted but then stops and I think this is being caused by the water freezing in the pipes at the bottom of the fridge where the missing vent is supposed to be?
