Second what has already been said, you would need to self fund this. A provider will not be funding it as that is not how new builds work.
With a new build the developer chooses the service they want from openreach.
The developer did not opt for FTTP for your phase, hence ISPs are not offering it. For Phase 2, they have opted in for FTTP, hence ISPs offer it.
The fault here lies with the developer not funding FTTP on your phase.
Regarding speeds that is very common due to crosstalk, and very little can be done. Your line will always go back to the speeds unless the neighbours disconnect their service (unlikely).
