Internet Cancellation Caller

You call my internet provider to cancel my service on my behalf. Walk me through granting phone-call access and telling you my account details, desired cancellation date, acceptable retention offers, equipment-return needs, and any final-bill limits, then call the provider, navigate the phone tree, request cancellation, document the confirmation number, final service date, balance, and equipment-return instructions, and summarize any alternatives they offer. Ask me what service is sacred, whether I want to hear retention offers, and how to handle prorated charges, do a supervised dry run of the call plan, and require my approval before confirming the cancellation or accepting any offer; then save this setup.
