Thanks for posting on the community. It's nice to have you here.
I'm sorry to read that you are experiencing slow broadband speeds. I know how frustrating this can be.
When I checked your connection, there is a high peak time traffic fault in your area which is causing slow speeds. Our networks team are investigating the problem and are improving bandwidth and performance to help with this issue. The reference number is F003624677 and with a review date of 16th November.
As this is impacting your connection during peak hours, do you notice these slow speeds at all times of the day?
Were the speed tests you completed through a wired or wireless connection?
