@Techwizz I have no problem explaining the laws of physics to you nor the difference of the conductivity between aluminiun, copper and the different frequencies of transmission when the 55Mb cap is lifted from VDSL connections.
How long have you got to spare because I seriously don't mind, it only took me just over 5yrs.
Just want to say that there was no solution or closure to this issue, I'm now stuck with 10% less speed than I originally had even after going back to the original 55/10 package.
It would be nice, but they flat out said that wasn't an option unless there was physical damage to the line, as it would disrupt many other's service. The last engineer pretty much just said "50 is a good speed and you should be happy with it, nothing we can do to improve it".
