Broadband connecting but can't do anything - HELP ...

Question

I've been using BT Broadband with the HH2 for about 6 months now and have had very few problems, but last Friday I couldn't do ANYTHING online. The broadband connection appeared to be OK (all blue lights lit on HH2) and nothing had changed with my hardware, but I couldn't get any data through. I tried my other laptop but it was the same. I tried both computers using wireless and wired connections to the HH2, but no difference. 
It appeared that some data is being exchanged - trying to open web pages sends a couple of hundred "packets" but only maybe 10 packets are received, according to the Windows connection status window (I admit that I don't know how accurate this is!).
I phoned the BT Broadband helpline (India?) and spent 4 hours doing al the usual software testing (ping tests etc) and internal wiring tests (using the master socket) but these guys were at a loss about why I can't use the broadband. They said that the line looked OK from their side, and that the broadband connection was OK. I even tried a different ADSL router - one I know that works - in case the HH2 box was faulty, but this didn't fix the problem either.
So now I think that there's something wrong with the line, or the exchange.
Does anyone know how I go about getting BT to take me seriously and send an engineer out?
When I asked about this, the guy on the Broadband helpline said that it's probably spyware (!) on my laptop that's causing the problem. I argued that this didn't sound plausible, but he was adamant that the problem is out if their hands. 
Any advice / help on this would be appreciated as I'm getting married in a 6 months and the fiance is in the middle of organising a load of stuff on-line. My life will be made a misery if I can't get this resolved as I'll need to be dragged around a load of shops!!

Answer 1

can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester http://speedtester.bt.com and post the results.
are you connected to the master or test socket or somewhere else
Someone may then be able to offer assistance
