If you are still in trial and find that your billing information is not saving correctly, we suggest that you please contact our Support team.
They will assist you in troubleshooting the issue, and provide you with information to get you on your way.

If you have an existing Pipedrive subscription and your information will not update correctly — or you are being given an error — you may wish to instead contact your card-issuing bank (or, if paying by PayPal, then contact PayPal) and inquire about any issues.
If that does not provide sufficient answers, please contact Pipedrive support and they will work to provide some further information, if possible.
