    Large cable termination

    fridge too large to move

    Who could dismantle and remove a large fridge freezer? The previous owners left it when they vacated and it has now broken. Our kitchen is in the basement and we think the stairs were replaced after the fridge was moved in as it now will not fit out by a long way
