CozzyKing. Some sort of giant fuck up by the sound of it!!! How come nobody checked to make sure it was the right lock-up to demolish? Usually before demolishing someone checks to see if there is anything inside the building. The metal car parts would normally be seperated from the bricks/blocks/timber etc not all mixed up together as it costs more to dispose of it like that.You must be gutted but at least you can claim for the parts that have gone.You will never be able to find all those parts again so make sure you get the right amount of compensation.
