Oh no, it would really sadden us to hear if your Cashback expired :(
As all Fave Cashback, e-Cashback, Partner Cashback and eCard Cashback have a fixed validity period upon issuance, they can only be utilized before their expiry. Once any Cashback expires, it will be automatically voided and cannot be reinstated.
Should you have any inquiries or need any help about a particular Cashback in your account, please reach out to our Customer Happiness team within the Cashback's validity period, for the team to assist with any issue that you are faced with before the Cashback expires.
