My apologies that you are experiencing slow broadband speeds. I know how frustrating this can be.
I've managed to locate your account and 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 F004732833 and with a review date of 21st December.
As this will impact your connection during peak hours, are you able to complete speed tests whilst the Hub is in modem mode please to see if the speeds differ?
