Due to some reason i have cancelled the order on the same day ie on 01.06.2020. I have received a confirmation mail of cancellation order no.[protected]).
There after on 06.06.2020, i have received a mail from amazon.in with the refund reference no.#169809, confirming that the refund of rs.1008/- has been successfully processed on 01.06.2020 and the amount should reflect in the account now.
