Probably not much you can do.
Your router is indicating a downstream line attenuation of 63.5dB (the highest figure it will read - your actual attenuation may be higher).
This shows your line length to be much greater than 1.5km (probably closer to 6-7km).
Your service is not capable of 8mb, it's an "upto" 8mb product.
The actual speed, as is made clear on BT's website (and on most other ISPs, too) will be heavily dependent on the length of your phone line.
Other factors are cable material (most are copper, but a lot of aluminium was install in the 1970s (this performs worse than copper, with ADSL).
There are a some things you can do, to get the best out of your line.
Connect the router to the test socket (inside your BT master phone socket).
If it connects faster, let us know, and we'll tell you how to make it permanent.
Unfortunately the facts are, if it's the length of your phone line that is keeping your speed down, no amount of yelling at BT will fix it - They're not going to be able to move the exchange closer to your home.
EDIT: Your speedtest result shows almost 700kbps, which is about as fast as you'll get from a connection speed just under 1Mbps (which is what you have).
So, the connection's performing very well for the line length - You're probably just stuck with it.
