### Answer
I'm sorry to hear about the difficulties you've encountered. Unfortunately, I don't have direct access to account-related issues or the specific booking process that led you to a representative from a different company. For immediate assistance with your account and to resolve the issue regarding adding a credit card, it would be best to directly reach out to the dedicated support team again, as they have the necessary tools and access to provide specific help and guidance.
For general guidance on creating assistants or managing phone numbers which could be related to your booking intentions, you might find the documentation links on [Creating an Assistant](
) or [Managing Phone Numbers](
) useful. However, please note that these resources are more technical and related to Vapi's development capabilities rather than customer support or account management issues.
