So the rep hasn't responded yet, how should I respond?

You don't know what the response will be.

What If It's In your favor, with a refund/replacement In progress? Your reply may well ruin the entire SE. Issue a friendly reminder stating that you're still waiting for the matter to be resolved.

The last email I sent ended with, "I will try to ask another carrier if they can ship it without telling them about the damage." I was thinking he was waiting for me to ask them and then update him on how it went.
