Would you trust an AI agent to negotiate your monthly bills?

I’m exploring an AI agent that helps people reduce recurring expenses such as internet, mobile, insurance, and software subscriptions. The agent reviews your bills, identifies where you may be overpaying, contacts providers on your behalf, negotiates better terms, and asks for approval before accepting any change.

I want to understand whether people would trust an agent to communicate and negotiate with service providers for them. What level of control would you need before connecting your accounts or sharing bills?

The biggest friction was not negotiation itself, but collecting account details, waiting for support, and comparing offers. My current hypothesis is that people will delegate the process if they remain in control of the final decision.
