Is there an email to reach out to for AC regarding an existing damaged bag claim?

P2 submitted a damaged bag claim to AC since the entire hardshell cracked which was reviewed by Canada Luggage Depot but was punted back to AC due to being "unable to find a suitable repair or replacement for the baggage".

It's been almost 2 weeks since receipt of this email with no further communication from AC so would like to follow up but the notification was sent from a do-not-reply email.

Any leads for contact would be greatly appreciated!

TIA
