The document provides guidance on using the Deardorff tool to handle port in promotion escalations and outlines the following: - Tier 1 can reprocess access requests and Tier 2 can reprocess and approve override requests. - The tool can be used to create new registrations, monitor status, escalate denied registrations, and ask the Promo Help Desk for assistance. Agents can search by BAN or PTN and escalate registrations by modifying details and resending to CRM or requesting a Y,Y override. - Situations requiring escalation include denied requests that are now resolved, incorrect amounts or PTNs, manual registrations requiring overrides, pending registrations needing overrides
