Pre lease clean

Soooo I collected my new unit keys today, I went to have a look and the carpet was not steam cleaned and the bathroom and kitchen not cleaned either. Throughout the lease agreement process I had requested to be there when the carpet was being steam cleaned as the previous tenant had pets, although the agent agreed this never happened. 

She claims there is an invoice (which fair to say if I knew a cleaner or had an ABN i could create too) i dont know what to do
