Here's the email they sent me:
"Hello,
It has been identified that your SDCC order has been double shipped, can you please return back the most recent order you received back. We already had a "Call Tag" setup for UPS to go to the ship to address in our records to retrieve your duplicate order. The first pick up attempt will be made tomorrow, if you will not be available, please give us a call if you will not be available.
Thank You,
NECA Customer Service"
I replied saying I have a job and asked if I could leave it outside or if they provide me with a UPS shipping label I'll drop it off. I also suggested adding their phone number to an email when they make a suggestion to call. Since they didn't respond I left it outside this morning. I just received a response saying not to leave it outside. We'll see if it's still in front of my house. I don't mind helping with the mistake, but I don't think I want to work with their customer service for a quality control issue. I didn't make the mistake here so I'm not going to drop everything to fix it or dig for their phone number to tell them I won't be home.
