i have received a demand notice for TDS not remitted by the deductor.Despite giving proof of deduction and details of deductor, the AO is not cancelling the demand notice issued under section 1433. CBDT has clearly issued press release that such demand against the assessee is against income tax law, the AO is adamant. what shoul be my next action?
