Hi owngrfld
Very sorry you have had such poor speeds for so long - I can certainly understand your frustration with this. Unfortunately, what you have been advised before is correct - only Openreach can get the infrastructure sorted to get your fibre. We can only order fibre if Openreach show it as being available for your property.
I'm guessing this has already been done - but you can submit a fibre availability form here, in which there is an option for "My neighbours can get fibre but I cannot". You can send that off directly to Openreach and query why the infrastructure has not yet been put in place.
Now, having said that, you did mention that your line was noisy. A noisy line would be an indicator of a fault and could be compromising your broadband speeds/stability further. I know you have contacted us various times, but if that noise has not been sorted I would recommend contacting one of our livechat technical agents here.
Regards
Ryan
