Initially, I would express my gratitude to the sales manager for bringing the issue to our attention and request additional details if necessary, such as screenshots, the exact steps taken prior to the error, and the device used. Next, I would attempt to replicate the error on multiple devices and browsers to evaluate the extent of the problem. After gathering sufficient information, I would report the issue to the technical team. The aforementioned steps enable me to provide the tech team with a clear description of the issue. It also facilitates a discussion regarding the situation, its causes, and the necessary actions to be taken. At the same time, I would recommend that the customer service team notify users who call about the issue that we are aware of it and are actively working on a solution. The communications team should also prepare a message to inform users through the app, email, or social media about our efforts to resolve the unexpected problem. Finally, once the issue has been resolved, I would collaborate with the tech team to investigate the root cause of the error and implement measures to prevent its recurrence.
