Faults in BT Broadband Network Equipment

Question

After having suffered BT Customer Services 4 times in the last 2 weeks, I am after some advice as to the best way to raise Broadband faults, so that I am prepared for the next failure.
In the last 2 weeks I have lost broadband connection 3 times, for 6 hours, 72 hours and 32 hours respectively.  In each case the fault was entirely within the BT Broadband Network, and was corrected without any actions by myself.  In each case the service went from perfect operation to nothing and back to perfect operation.
The service status pages either lag several hours/days behind, or fail to mention my STD code.
Is there anyway to raise these issues, or wording I can use to avoid the pain, irrelevant questions, and in the last case the insistence that there was a fault in my property and the arrangement of an engineer visit (which I had to cancel myself)?
The script followers on the phone or chat lines refuse to carry out any checks of the BT Broadband equipment, and just insist that the fault is at my end of the service.  The most frustrating part is that there is no feedback.  It would be nice to be able to go back to the individual who wasted 30-60 minutes of my life, and point out that their analysis, and tests were completely wrong, and that the fault was resolved by BT either by the restarting of something in the BT broadband network, or as the unintended result of another action.

Answer 1

Reading through the recent forum posts I can see that my issue has been different to many others, who are experiencing physical line issues.  I my issue occurs again I wil update this post.
In the meatime this is a motoring analogy of my issue, if BT managed the roads and traffic flow:
I am driving on a motorway at 70mph, and all the traffic stops, and after an hour there is no sign of it moving. I call BT to find out why the traffic has stopped, expecting an answer along the lines of, there has been an accident but it should be clear in a couple of hours, or there is major congestion ahead of you due to heavy traffic.
However, BT’s response is that we have run some tests, and found that your car is not moving; therefore the issue is with your car, not the motorway. Have you checked that you have not run out of petrol, or that you have a puncture? When I explain that there is nothing wrong with my car, their response is that there must be, so we will send out our recovery service in 2 days time to check that your car actually works.
In the meantime the accident/congestion is cleared after 2 hours and I return to driving at 70mph.
