As you mave already been told in your other thread BTRetail (your ISP) cannot help you with this. It is the remit of BTWholesale to provide congestion relief.
BTW will bw aware of it and have plans in place, how long it take depends on the complexity of the work needed.
Yep this is still broken after they apparently fixed it, then trying to say it's broken is BROKEN. Not missing anything so they probably did it intentionally just so people can't complain, wouldn't be surprised.
