# How can I find out who marked a customer as 'Do Not Service' and when it was done?

## Problem

I need to know who and when changed the customer's status to "Do Not Service".

## Solution

#### Open Audit Trail

1. [Search for](/v1/docs/use-search-in-servicetitan) and open the customer record for which you want to view changes.
2. From the left side menu, select **Audit Trail**.

> [!TIP]
> **Tip:** Use the date and username filters to narrow your search. For more, see [Use the audit trail on customer and location records](/v1/docs/use-the-audit-trail-on-customer-and-location-records).

> [!NOTE]
> **Note:** If the change happened within the last 14 days, you can contact ServiceTitan support with the customer's name so we can help you verify the information.
