Every time a service is added or removed from my TalkTalk landline (VOIP over full fibre), caller display stops working. I have now contacted TalkTalk customer support via online chat three times over the last two weeks. Each time they say it's a "known issue" and have corrected it and to try again after 24 hours. It still does not work on either my physical DECT phones or on the TalkTalk app. All incoming calls show as "Anonymous/Unavailable". If I dial 1471 then the last number that called me does work. If I check on My Account it says that I can't make any changes as one is outstanding. Is there anyone from TalkTalk on here that can fix my issue as I really don't fancy another hour on the chat system getting nowhere fast. Thank you.
