BT ?!?

They don't know their @r$e from their elbow !!!
After a week of every evening from 7pm until calls transfered to India (or wherever) at 10pm, trying to sort out internet at home I was offered 256k at best.
They kept saying my line was tied to another provider, or was 'tagged'. (This was a brand new line they'd installed a week earlier.

)
By chance I found a scrap of paper left behind by the 'Open Reach' techie who'd installed the line so I called the number and got through to a techie who, although rather surprised to have a member of the public come through on that number, was very helpfull and after running some tests called me back and advised I should get 6Mbps easily. He suggested I choose any provider and he'd sort out any unacceptable speed issues afterwards.
I signed up to Tiscali (inc. line rental) and got 6.9Mbps straight away. When I re-signed they sent me a wireless modem and since then I've been getting around 16Mbps. I've had no issues with service or connection.
