How do i make income tax officers understand?

i buy waste paper from local waste paper shops and send it to paper mills for recycling. Now, an idiotic income tax officer ( tooooooo brainy for me to even understand what he wants ) wants me to furnish bought note purchase accounts for the year 2008 – 2009 .
Can i tell him it is not at all possible as the petty shops do not keep account? :/
If so .. Please help!
