Did your upgrade go as smoothly as you'd hoped?
I'm currently disconnected. I've had FTTP through an ECI ONT for nearly 10 years. I've wanted to upgrade for the last four years, but didn't want to go 14 days without internet, so I read your post with interest, and found it after I'd already written to the CEO of Openreach to describe the problem, and hope for help.
To cut the story short, I did get a call from someone at Openreach, who also put me onto someone in the BT Executive Complaints Team, but I've not been as lucky as you.
So currently I've been cut off for 7 days. My ONT still appears to be live/synced. I'm just hoping that after another 7 days my ONT will become deregistered and I'll be able to order gigabit speeds. It's all a bit up in the air at the moment. If it doesn't work I'll have to go back to 330Mbps, and try again.
Do you know if the Openreach engineer came to your property to replace your old ECI ONT before it had lost sync? Did he deregister it on site? This is the thing I've not been able to do, which is why I'm just hoping, with fingers firmly crossed, that after 14 days my ONT will deregister, similar to what I've read other people do in these forums.
I hope it went well for you, and you're enjoying your new speeds! 🙂
I'm down in Cornwall, and almost everyone I know, who has FTTP, has an ECI ONT, and faces the same issue, as we got fibre quite early, down here.
