Can understand the frustration if the phone queue is that long.
Would probably have tried PN details in router (esp if Aquiss confirmed it was no longer with them) but understand that there's still some way to go for smooth transfers to work, and how one can be left in the dark for some time.
FWIW, when I moved (out of my old place on 22/12/11, to stay at sister's home for 2 weeks then go into hospital) and then to get into new home on 23/01/12, PN were in contact week in week out (because every 7 days the ticket system would pop it in someone's queue of jobs) where I had no way to even give them the number of the line I was getting in new home...
Primus didn't even tell me line was active (I was using Three dongle at the time to check all my mailboxes) but once I knew it was, and the number, PN moved swiftly (but again one gets no call from Openreach - which would really be a nice touch if they could be bothered) and the ISPs probably depend on some queue of messages coming back from Openreach to update status on thousands of lines each week/month, so the delay (between line having active broadband service possible, and ISP being told) are perhaps not PN's fault.
If you run a business, have a second ISP and backup web hosting...
