Im trying to send a text to a 5 digit number and i get a response, "Service Access Denied", why?

Hey there, folks! There is a short code block that can appear on an account.  I'm not sure if the store has access to the tool used to remove it.  You'll need to reach out to 611 or T-Force to check and if short codes aren't blacklisted, they can file a trouble ticket for you.
