Does Caller Display show as active when you log into your My Account? If it does then could you try removing this, waiting for 4 hours and then try re-adding this again please.
From the 29th of March our TalkTalk Community will move to peer-to-peer support and the TalkTalk team will no longer be here to support with queries. Don't worry we still have plenty of ways to reach out if you need to speak to TalkTalk directly. For more details check out the link here: How to contact TalkTalk Broadband - Help & Support.
