Please remember to edit out your phone number before you post the results.
Its not possible for you to be wired to the wrong cabinet, as the external network is fixed.
"There is another cabinet nearby that is already accepting orders accepting orders, can I get fibre broadband from there instead?
No, the network over which fibre broadband is provided is bespoke, and all premises are served from dedicated fixed distribution points. Many lines are connected via their own overhead or underground link to a nearby green telephony cabinet. There are no interconnections that could be used to move a line from one cabinet to another."
Its possible that the database was wrong when you ordered.
If you can please provide the information I asked for, then it will become clearer.
