Fridge Freezer (Leiston IP16)

Our fridge freezer has had it's day, and is growing icebergs in the fridge compartment, which is freezing all my fresh fruit and vegetables, making a lot of them unusable...we are on benefits as my husband is disabled and I am his sole carer, we really need a working fridge freezer, don't mind what colour it is as long as it's large...!! We may also be asking for another few items in other posts, but this is really important to me as I am struggling to store food safely, and fresh vegetables and fruit are vital for us...thanks in advance to anyone who can help
