>> talk talk is unbundled aol
Since TT took over aol uk, then they have been using the TT dslams for LLU upgrades rather than putting in more AOL dslams. That bit makes financial sense.

Good for you, keep trying
Unfortunately yours isnt the only case Ive seen where AOL are doing this, and I have unfortunately seen many many more instances where AOL have tried fobbing off users re the upgrades. Not all of them have involved LLU.
The only thing that does seem to work is persistance and requesting your MAC. There are many other ISPs out there that would give you the maximum speed your line could handle - nevermind 2Mb - for the same £ that you are paying to AOL :/
Good luck and please let us know how it goes.
