On the rare occasion that our payment provider has technical issues, we switch to another provider to make sure that our customers are not inconvenienced. However, card details are not saved with this provider, so you will have to enter them again.
We normally switch back within a few hours, in which case the stored cards become available again.
Note: From September 1 2018, card details will be stored with all of our payment providers. If you continue to have this issue after September 1, please contact us.
