Hey @mcbjazz,
@goslow has beaten me to it and said pretty much what I would have also said.
I just want to clarify that there is no charge for adding caller display to your line.
I have checked your account and can see that the feature is active on your account, please can you double check to see if this feature is working or not and let me know if we need to look into this further.
Regards
Steven_L
