I understand, it's hard. But from the opposite end it can be hard for users to trust so you have to make that easier on them by being more transparent.

I'd suggest finding a perfect use case - maybe it's not T-Mobile. Then record a happy path video showing it working perfectly.

Also - as a tip, a lot of these companies will use the same software. So, right now your bot didn't do well with T-Mobile at all because it didn't know how to response to multi-button prompts. But once you teach it how to do that it'll know how to response to any company that uses the same software (LivePerson). Almost always you don't have to 'press' the button, you can just respond with the text of the button.
