I think you need to spend some more time testing this service if you are advertising this as a service that inherently interfaces with humans. I see that others in this thread like the applications for scambaiting, but I don't fully understand the use case you have here. If it's AI on both ends of the phone... whats the point of the call in the first place? It's not that hard to get a human on the other line who is able to help me far better than any robotic agent could.

If the agent has trouble solving "complex verification or (providing) documents" I doubt that a monthly fee for simple tasks doesn't sound like a viable and sustainable business model. It sounds like the anti-social bunch would like it but past that it's going to be hard drumming up a lot of support.
