I would think that the most likely cause of this is the way that the account has been setup. I have asked one of TalkTalk's support to pick your thread up and investigate it for you.
They aim to respond within 48 hours (Monday - Friday) excluding Bank Holidays, but if more urgent you can always try the Service Centre on 0345 172 0088. The posts are responded to in time/date order, oldest first. Please try to avoid posting on here until TalkTalk has responded to you, otherwise, this will just put you further down the queue.
To save yourself time, please make sure that your community profile includes your first & last names, & if possible an alternative contact number. This can be done by clicking on your Avatar picture then click on "My Settings" followed by:-
Personal Profile > Personal Information
Otherwise, TalkTalk will not be able to tie up your forum username to your broadband account. Only you & TalkTalk have visibility of your details.
In the private Notes section please include your future fibre order/account number as well as the serial number of your ONT.
