Hi, were you not credited after being debited for your last refill?
We have a Retry button built into the app that you can click on to retry crediting/refilling your OkadaBooks account.
Don't worry, you will not be billed twice. Please see the screenshots attached below
Please use the "Contact Us" option above if the problem persists. Don't forget to paste your support information while contacting us
Or you can send a mail to firstname.lastname@example.org and we'll get back to you. Thank you for riding with us
