We will send you an email whenever there is a failed payment on your account. When this is the case, please ensure the payment card linked to your account is still valid (i.e has not expired) and holds enough funds.
If the above looks all good, it could be possible that the bank linked to the attempted payment is declining transactions processed via Yoyo-powered apps. The payment requests are then rejected and no charge is issued.
In this instance, you will need to contact your bank and let them know you want to allow Yoyo Wallet payments so they can properly process future transactions.
