You can change your bank details, credit card details, or PayPal account details by clicking on
"Settings/Invoices & Accounts" (cog symbol in the left sidebar) followed by "Premium Billing". Then just click on "Edit" next to the item you want to change, enter your XING password to confirm the changes, and then click on "Save billing details".
If you encounter any problems, please note the following points:
- Make sure you enter numbers without any spaces or special characters.
- Even if you only want to change your credit card's expiry date you'll need to re-enter all of your credit card details.
- Don't forget to enter your credit card's security code.
- Please make sure you enter your XING password and save your changes.
Also make sure that your billing address is up to date and complete (all of the mandatory fields must be filled in), otherwise you won't be able to save your billing details.
