In the event of any transaction reversal, will the TCS amount be refunded?

In the case of any reversal leading to refund of transaction amount, the originally collected TCS will not be refunded; except, on the transaction where reversal is done on the date of original transaction itself. However, TCS credit for any tax collected by the bank (if not refunded) can be claimed by the card holder when filing the Income Tax Return, subject to applicable income tax provisions.
