When did the phone system change to fibre in London SE18. I have not had a letter, but my phone has been migrated, and I don't know how many days I have been unable to receive calls.
Welcome to the Community and thank you for posting.
I am very sorry to hear you have not yet received a letter regarding the migration of your phone, we would be happy to help.
I will need to check on things from our side so I am going to pop you over a private message to take a few details.
This will be available via the purple envelope on the top right of this page.
