Thanks for getting in touch, I'm sorry to see you have been having trouble with your connection.
I have taken a look and it seems you are affected by fault ref F004045933 for slow speeds at peak times. This is currently with the planning team so I don't have a lot of information currently. We should know more after 25/01/2017.
I have popped the details across to the team that deal with this type of issue and they will contact you as soon as they can with more information.
