Ted here from Shopify, thanks for reaching out to us!
Sure thing, I've just sent you an email there to help renew the domain. Please reply back to my email when you have a moment. When the domain renewal has been processed, I'd recommend enabling the auto-renew feature as mentioned in this guide for future convenience.
Just as well, if you would like to chat with our support; to help our merchants receive a faster response, we’ve moved some phone conversations to online chats, Facebook, Twitter and email support instead. You should be able to contact our 24/7 support here via the Help Centre by selecting Support > Contact Support tab in the main menu. Or our Facebook support can be found here.
If there is anything else I can help you with, please let me know, I'm happy to help!
Hope you're having a great day!
I haven't received a response to the email. Would you like for me to go ahead and renew the domain?
Thanks for letting me know. I've just emailed you there so I can authenticate the account and help renew the domain for you there. Please reply back to my email when you have a moment.
