Hi lewshann,
I am sorry to hear that you are experiencing speed issues with your broadband. I have taken a look at your line stats and can see that your throughput speeds, up to your property are at a normal: 10408 (10Mb). I would strongly advise following the <a href="http://faults.plus.net">Broadband Fault Checker</a> and completing all the checks.
If you complete all of the checks and your speeds have not changed, you can continue to raise a fault using the above tool.
I hope this helps you get to the root of the problem.
