This document outlines the workflow for calling customers regarding unpaid banking accounts. It discusses the allocation strategy for assigning unpaid accounts, the setup of the call center team, the calling and negotiation process, payment processing, penal transfers, and revoking ECS authorizations. The key steps are allocating unpaid accounts on the 1st of each month, calling customers, negotiating payment or waivers, processing payments made either online or at branches, transferring penal amounts as needed, and revoking ECS if payments bounce more than three times.
