Hi Everyone, thank you for all the help and advice! Much appreciated!!
The Clive Selley route suggested by jpm is a good shout, although as Taras cautions, if has been overused in past, maybe I should try a more official channel again first..
Given people's thoughts it sounds like there are a few different options for what has happened from a database error to an aborted install part of the way through.
I was all prepared to send the landlord link to my landlord and contact Openreach via the same form as a tenant and explicitly ask them to check what the situation with the building and please reply to me by email. (then would contact Clive if I didn't recieve a reply after a week or so)
But.. after Iniltous mentioned about the copper DP, I thought I would do bit more digging around in the communal cupboard when i got home from work.
I think this is the copper DP

and following the cable back to where it comes through a duct (in the same place as the fibre cable) there is a label on the thick black copper cable dated 20/4/15. So this means the copper was installed over 18 months before the fibre line which is dated 21/11/17.

Would I be right in thinking there is no way Openreach would install this (after the original building of the block) without a wayleave, so there must be one in place? so it must either be a database issue or a aborted install for some reason? (if it is a database issue, perhaps they can sort pretty quickly?)
unfortunately most people in the block rent, so no one around from back then!
Any other company I would just ring them up to try and explain the issue, but not an option with Openreach, so not sure weather to brave the online form again and perhaps say there is a database/install issue rather than asking or hope they don't ignore my question about a database issue again (if they do, then going to Clive) or weather to use one of the apartment MDU forms to contact them.
