If you are unable to pay using Boost for your Fave transactions, this could be due to:
i) You may have insufficient funds in your Boost Wallet to make the payment. If so, please top up your Boost Wallet before attempting another payment.
Otherwise, you will be redirected back to the payment page, and prompted to use alternative payment methods such as your credit / debit card or PayPal.
Alternatively, you can reach out to the Fave team at firstname.lastname@example.org or initiate a live chat and their Customer Happiness team will assist you.
