Hello!
I'm here to help you with your billing issue. It sounds like you've already added a payment method, but you're having trouble adjusting your monthly limit. This could be due to a few different reasons, such as restrictions on your account, issues with the payment method, or a temporary service problem.
To resolve this, I would recommend checking the following:
1. Ensure that the card you added is valid and has sufficient funds.
2. Verify if there are any restrictions on your account that might prevent changing the limit.
3. Check for any notifications or alerts in your dashboard that could provide more information on the issue.
If everything seems to be in order on your end, it might be best to reach out to our support team for a more detailed look into your account and assistance in resolving the issue.
Would you like me to guide you on how to contact support or is there anything else I can assist you with right now?
