### Answer It appears you're encountering issues with the billing limit on your Vapi account, particularly with changes not being saved or recognized. A similar situation was discussed in the Discord community where a user faced trouble with the billing limit error despite making adjustments to their billing settings. They suspected that despite changing the limit on the billing page, the backend still retained the lower value, causing continued errors [(1)]() . Another user encountered issues with their phone number not working due to reaching the billing limit, which wasn't immediately obvious to them [(2)]() . While these discussions suggest that updating payment information and adjusting billing limits should resolve the issue, persistent problems may require direct intervention from the Vapi team. It's also highlighted that ensuring the correct card details are saved and possibly trying different cards can help [(1)]() [(2)]() . Given the nature of your issue - especially with card details being automatically removed - I recommend double-checking your billing settings to ensure that the changes are correctly saved. If the problem persists, it might be similar to the backend issue discussed in the community, although direct intervention from Vapi's team would be necessary in such a case. Unfortunately, without direct access to account details and backend systems, further specific assistance cannot be provided here. The scenarios shared from the Discord community suggest that such issues may require a closer look by the Vapi team to resolve.
