24/7 Autonomous Customer Service with Agentic AI Agents

Executive Summary 

A leading global bank faced growing customer service volumes, rising operational costs, and inconsistent support experiences across languages and regions. To modernize customer interactions and ensure around-the-clock assistance, they deployed Agent analyst and Agent search on a context-first agentic infrastructure to build 24/7 AI-powered customer service operations. 

AI agents engage customers via voice, chat, and email across multiple languages. They autonomously greet users, authenticate identity, retrieve account information, identify potential fraud, block compromised cards, and initiate refunds — all without human intervention. 

An agent analyst interprets the customer’s intent and context in real time, while Agent search retrieves precise policy, transaction, or procedural data from internal knowledge bases. When complex cases arise, the agent escalates seamlessly to human representatives with full context retained. 

This deployment reduced average resolution time by 60%, improved customer satisfaction by 35%, and decreased call center operational costs by 40%, enabling the enterprise to deliver always-on, multilingual, and compliant customer support. 

Customer Challenge 

Business Challenges 

The customer, a multinational financial services firm, struggled with inconsistent service levels and growing support demand across time zones and languages. 

Key business problems included: 

• High support costs: Maintaining large 24/7 call centers was costly and inefficient. 

• Long resolution times: Agents spent excessive time switching between systems and searching for information. 

• Inconsistent experience: Quality of service varied by region, agent experience, and language proficiency. 

• High churn risk: Poor service response and delays led to low Net Promoter Scores (NPS) and customer attrition. 

Business goals: 

• Deliver consistent, real-time support in multiple languages. 

• Reduce customer handling time (AHT) and improve first-contact resolution (FCR). 

• Enable autonomous resolution for routine requests (balance checks, refunds, card blocking).

• Scale service operations without proportional cost increases.

• Legacy IVR and chatbot systems are limited to keyword-based scripts. 

• Manual escalation and ticket creation. 

• Fragmented knowledge bases and inconsistent data access. 

• No real-time fraud identification or contextual awareness. 

Compliance and business pressures: 

• Financial regulations required secure, auditable customer interactions. 

• Data residency and privacy compliance (GDPR, PCI DSS) were mandatory across regions. 

• Customer SLAs demanded rapid, consistent response across all communication channels.  

Technical Challenges 

Infrastructure and System Issues 

• Disparate CRM, ticketing, and fraud detection systems. 

• Voice and chat systems lacked unified AI integration. 

• Knowledge bases are stored across SharePoint, Confluence, and legacy databases. 

Technical Debt and Limitations 

• Old NLP engines with poor multilingual support. 

• No unified data model for customer context. 

• Manual rule updates for chatbot intents. 

Integration and Data Management Issues 

• Lack of API-level integration between fraud, payments, and support systems. 

• No contextual memory between chat and voice interactions. 

• Fragmented access control and identity verification workflows

Scalability, Reliability, and Performance Limitations 

• Could not handle high concurrency during transaction surges (e.g., salary days, holidays). 

• Limited ability to perform sentiment analysis or adaptive response generation. 

• Inconsistent handover to live agents caused repeated queries and frustration. 

Security and Compliance 

• Unencrypted voice logs and partial masking of sensitive information. 

• No audit trail of AI agent decisions. 

• Weak integration with enterprise IAM for access control. 

Partner Solution 

Solution Overview

The organization deployed Agent Analyst and Agent Search to power an agent-based AI customer service system. 

• Agent analyst: Understands customer intent, validates user identity, and performs contextual actions (account check, fraud block, refund initiation). 

• Agent search: Retrieves relevant information from structured (CRM, ticketing) and unstructured (emails, docs, knowledge base) sources to provide accurate responses. 

Together, they: 

• Enable seamless omnichannel communication (voice, chat, email). 

• Auto-translate interactions into customer-preferred languages. 

• Detect and act on fraud indicators in real time. 

• Generate contextual summaries and escalate complex cases with full history. 

This multi-agent system transformed the support process into a real-time, context-driven, autonomous workflow — improving speed, accuracy, and personalization. 

Targeted Industries 

Recommended Agents 

• Agent analyst → Intent detection, contextual decisioning, workflow orchestration. 

• Agent search → Retrieval from knowledge systems, documentation, and transaction history. 

Solution Approach 

Multi-Channel Engagement 

• Integrates with telephony (VoIP, Twilio), chat (Slack, WhatsApp, website), and email systems. 

• Detects user intent and context from voice tone, language, and text patterns. 

• Auto-authenticates users via OTP or voice biometrics. 

Contextual Decisioning 

• Agent Analyst interprets user requests and triggers secure backend workflows. 

• Validates fraud indicators (e.g., unusual login, multiple failed PIN attempts). 

• Blocks compromised cards and initiates refund workflows autonomously. 

Knowledge Retrieval 

• Agent search fetches up-to-date responses from knowledge bases, transaction logs, and policies. 

• Ensures accuracy through semantic search and source attribution. 

Escalation and Continuity 

• Escalates to human agents with context summary and user sentiment. 

• Preserves conversation state across voice, chat, and email.
