I'm sorry to hear that you're experiencing issues with the assistant creation and outbound call charges. To better assist you, I would need some more information about the specific steps you're taking when you encounter this issue. Could you please provide more details on how you are selecting the mode in the assistant creation and the exact point at which it changes from Twilio to web?
In the meantime, please ensure that you are following the correct procedure for setting up the assistant with Twilio integration. If there's a configuration issue, it might be causing the assistant to default to web mode, which could explain the unexpected charges.
If you believe there might be a technical glitch or if you need assistance with reviewing your Twilio billing and charges, I recommend reaching out to Twilio's support directly for a detailed investigation into your account activity.
If there's anything specific you'd like me to do to assist you further, please let me know!
