how long ago was that change

Aha she did not do that, just seems a bit harsh to shut down access less than 48 hours after migration and before final direct debit has been processed, and more so if someone is still paying for the notice period.

I migrated out to BT in February this year because it was the only way to get my native FTTP installed without paying excess construction charges. I wanted to keep my account so that I could potentially migrate back when my BT contract ends.

Thanks - that is very interesting and is a useful pointer for the future
