New Fibre Install. Went Well, But............

[#1]

I can't remember who was to blame to be honest, was a bit annoyed so just listened when t was explained that a request is intiated on the Plusnet system, and should then be picked up by Openreach. There are some excellent suggestions within that thread.

Well Openreach engineer, has come and gone. Carried out checks on his JDSU and they all passed. He then went off and and checked a few joins on the cable run, and said that he re-terminated some and had got a few errors down. Net result = not much difference. He reckons that for the line length that what I am getting is pretty good. I have included the latest wired speed test results. I note that the IP profile has risen slightly. Can a PN staff member take a look and decide what the next step is? Many thanks.

I know that you have passed the fault back to Openreach, but from going from a estimate of 47Mb/s, to having 25Mb/s and now down to 22Mb/s is very dissapointing, please can you advise what the next course of action is.
