Welcome to the community. It's nice to have you here.
My apologies you are experiencing slow broadband speeds.
There is an SNR (signal to noise ratio) fault in your area which could be contributing to the slow speed issue. The reference number is F006623559 and has a review date of 16th October. As this is a review date it can be subject to change.
In the meantime, are you testing the speeds through a wired or wireless connection? If wireless, can you try through wired please.
