Ok so more developments. I checked the fault tracker this morning and noticed my fault had been marked resolved, I contact BT who tell me that the engineer has been cancelled for the second time, The reason being is they can see the hub is connected?? So someone decided to cancel assuming the issue had been resolved.
I did as you said and filed a complaint, they then offered me another appointment for Friday this time for an engineer but there is a decent chance this will also get cancelled again.
Its obviously as you say someone has switched my broadband to another customer or something so they are seeing a hub connected, shame its not my hub.
Well that really sucks.
Was it the overseas team again?
The way I see it, if they say they can see it connecting from their end to the hub and you are getting the Yellow (Orange) light, its obviously an issue at the exchange with the line card / port is being used on another line and they system hasn't been updated to reflect this.
So their system says line card X is linked to your line, when in fact its linked to another.
The next time you speak to them, ask them to get the serial number of your connected BT Hub remotely, as far as I know they can do this remotely.
This would indicate if its your hub they are talking to, my guesses it will be a different number.
The serial number is on the bottom of the hub 4 on the white label.
Maybe a BT engineer can clarify this s little on how it all works.
All I know is when I was without broadband for say a few weeks when I left Zen and got BT, my Modem still synced up to the exchange, and it just failed to authenticate, so this would indicate there was a line card / port still linked to my line, and about 3 days before the broadband started with BT, it failed to even connect, then about a day or two before the start date it started working again and I had broadband.
So yours should at least do the syncing with the exchange part.
When you connected the Hub4 and the 3rd part modem what did they say in the logs?
TBH, I would of put this down as a faulty hub, but where you said you brought a 3rd party modem/router and that also fails, rules out a faulty hub.
Have you done or installed anything before or around when the issues started?
