Well I gave up and phoned on Wednesday to move "up" to Karoo Mid 2 from Max, so that my streaming works. I get told a date, confirmed by letter, of 7th May. Yet I see my router has already moved to ADSL2+ and sync of 5.5mbps (as opposed to ADSL and 4.5 before).
And as I predicted to them, it's unstable, we did this test quite a long time ago, and it just drops off, the SNR is 6.5 at best. So now I have a whole weekend of connection up, connection down, and obviously this is no good for watching streams!
I have lost all faith in this company.
I assume there will be a profile of about 4.5 for ADSL2+ they can put me on.
