Executive Summary

CKB Bank's Customer Care & Customer Experience team handles complaints every day: the kind of messages where tone matters as much as speed. Writing a careful, empathetic reply used to take time the team didn't always have. With Lexi Supporter drafting the first version, replies come faster without losing that care, and the team's own numbers, and their clients' replies, show it.

About the Company

CKB Bank

CKB Bank (Crnogorska Komercijalna Banka a.d. Podgorica) is one of Montenegro's leading banks, part of the OTP Group. Its Customer Care & Customer Experience department, based in Podgorica, handles day-to-day customer complaints and support requests.

The Challenge

Clients Deserved Better Replies, Written Faster

CKB Bank's team decided their clients deserved better replies to complaints, not just faster ones, but ones that got the tone right. That was hard to do consistently under time pressure.

  • Standard complaintstook 10–15 minutes to write, start to finish.
  • Complex complaintscould take up to an hour to get right.

Getting the tone right on harder cases was where agents struggled most, and where clients noticed most.

The team decided to try Lexi's customer support model to see if it could close that gap.

The Solution

Lexi Supporter Drafts the Tone, Agents Finish the Reply

Lexi Supporter reads the emotional tone behind an incoming message and drafts a reply built for that tone, whether that means calming down a frustrated client or clearly answering a confused one. The agent still reviews, edits, and sends every message. What changes is that they start from a draft that already gets the tone right, instead of a blank page.

CKB Bank's agents used Lexi Supporter specifically for drafting replies to client complaints.

The Results · Time

From an Hour Per Reply to Minutes

Across the board, CKB Bank's agents spent 70% less time writing responses. Broken down by case type, the drop looked like this:

Standard complaints, most cases10–15 min3–5 min
The most complex complaintsUp to 1 hour10 min

That time savings let the team focus on communication quality and other work, rather than just getting through the queue. Response time to clients overall dropped by as much as 85%, which directly speeds up how quickly complaints get closed.

Clients Noticed, Too

Client satisfaction with complaint replies has noticeably increased. CKB Bank's team reports that client feedback has been extremely positive: replies are rated as clear, professional, and in line with what clients expect. Clients respond more often, because they feel recognized and understood, and the empathy built into Lexi-assisted replies encourages them to share more information, which makes complaints easier to resolve.
