As a call center agent you have a script that you must read to customers

from a computer. A customer calls with an issue but your computer screen
is freezing and moving very slowly making it difficult for you to address the
issue as scripted.
Most Take the call with a slow-moving script although the call will have pauses
Put the customer on hold until the script loads
Apologize and tell the customer that your system is running slowly; ask her to call back
Ask the customer more questions to allow the screen to unfreeze

I apologize for the inconvenience, but it seems that my computer system is running slowly at the moment. To better assist you, may I kindly ask you a few additional questions while the screen catches up? Please bear with me for a moment, and I'll do my best to address your issue. Thank you for your understanding.
