Internet Connection down shortly after install / O...

Question

I ordered Infinity a couple of weeks ago, and the Openreach Engineer visited a couple of days ago.
The install went great, and the speeds I got during were AMAZING!
However, about three hours after the engineer left, my HH3's Broadband Light light changed to a steady Orange, and I lost all Internet Access. I called the Support and they said this was because things don't go properly active until Midnight. (This seemed odd, as it had worked perfectly during the afternoon).
The following morning it still wasn't working, so I called the support again, and they said it was because the OpenReach Engineer hadn't updated his notes to say he'd completed the job.
Another 48hrs later, (3 of which spent on hold to BT), I'm no further finding out what is wrong, or when it's going to be fixed. All I get is "Your job is still open, that's why it doesn't work".
All the order-tracking website says is "Your Broadband order is in hand with a member of our team, if there are any issues we will contact you. Please continue to check online for further updates".
Any ideas how I can get ANY info from BT as to when this might get fixed? Is there a magic number to call? ;-)
Further Info:
All 3 lights on the VDSL Modem light, so it's getting Sync. (I originally thought it may have overheated, and that's all the problem is).
Does anyone know what the default IP of it is, or if it responds to ping? Plugging a laptop directly into it and pinging the Broadcat IP of all the private IP ranges doesn't find it - so I'm wondering if it IS just the modem that's broken?
Thanks in advance!

Answer 1

I don't think its your modem, as you say you have 3 green lights... Its looks like what BT told you is correct .i.e. If engineer for what ever reason has not closed job correctly, BT think your line has not been installed, the only way to sort this out is to make another appointment and when engineer calls up to say they are on the way, tell them no visit needed, just please close job off complete.... Now really BT should be able to do this over the phone, however because the work is done by Openreach this causes problems ( one of our managers had the same problem and it took 3 attempts to finally sort out ).... Just on the off chance you could try turning off just the HUB and then see if when switched on it goes straight orange or goes red/purple ( this is the hub authenticating )... Good luck
