BT manage to give incompetence a whole new definition.
I get to about 1.3gig and it will just freeze everytime.

LOTS of people complaining that their service has deteriorated significantly since the "upgrade".
No, unlike Virgin, BT are trying to get everyone the best speeds possible on their line. If this was virgin they would just throttle connections to solve it. At least give it 10 days since the 80/20 upgrade then judge BT on their service.

Regardless of protocol and application?

I call BT up, get through to sales because the automated voice phone system sucks. Woman does understand what i am trying to say, ends up hanging up on me. Typical, so i call back, get through to a friendly guy who says i need to speak to customer options. Transfer me through, i wait 10 mins on hold. Reception picks up. Start again, give my details ask me why i am phoning and he argues with me as he thinks i should speak to sales, i tell him sales just told me to speak to customer options. He transfers me to customer options, wait 30 mins on hold. I hang up.
BT i just hate them. I want to get the free upgrade, but BT are already starting **** by saying my contract started after the 3 month free, so if i eventually get through to someone who is capable of doing something, i will probably, break my internet, end up with an additional 12 months on my contract and who knows what else, have to ask myself if it is worth the extra bandwidth.
The next day i had my profile changes 
Doesn't sound like it, when I check mine it gives me 77.43 Mbps.
What date did BT give you?
Should have been done by Sunday/Monday. The guy in the call centre assures me we have been upgraded but I'm sure he doesn't know what he's talking about.
Is there a twitter account or a forum that the BT engineers respond on?

Is there any negative impact to turning QOS off?
