apparently I was going to get faster speeds
For what reason? Were you on an up to 8 Meg ADSL Max product before? If you were already on ADSL2+ there is no reason you should get faster speeds.
All your stats are good except:
Downstream 862 (Kbps.)
You should be getting 6.4 Meg Down Sync here. That's the reason for slow speedtests.
The usual reason users get slow syncs on EE is the Down NM being held too high but your NM of ~6dB is correct. So I can only think EE has you on a banded profile. Tell them to take you off it and let it free-wheel.
