Hello, @CoffeeMike !
Karlie here from the Shopify Guru Team! I do apologize that the callback feature isn’t available at this current time. As that message had mentioned, the feature is only available depending on our current contact volume. You do have the option to contact our team via chat, email, Twitter or Facebook. You can be assured that we are working on it. We are trying our best to help every one - I am happy to help you out today.
I’m happy to answer any questions you may have, but it would be best to take this conversation to email so I can properly verify your store before I look into billing for your account. What I will do is reach out to you by sending an email to the email address you have on account for your Shopify Forums Community account. Be sure to reply back to that email so we can continue our conversation and so I can look into your store for you.
I will be in touch via email!
