Time to upgrade - but by moving on?

[#1]

Getting to the stage where I have to think about this - reluctantly, because my contract has a while to go.
Raised a ticket re speeds on my steam driven set up (as evidenced by latencies/pings etc) at the beginning of the week and still awaiting a substantive response to the query.
DL today quoted at 3.00 mb/s.
Suspect that the guilty party is (surprise, surprise) BT.
Therefore seems that, in view of other threads on this forum, I need to find a supplier where I won't be dependent on some hairy arsed engineer from BTOR.
I appreciate that a PN forum is not the obvious place to enquire, but have any of you guys any observations re shifting to (just as an example) fibre on Virgin?
