I've been with BT for 21 months now and recently noticed that downstream speed is set at 40Mbps where guaranteed speed I should get is 50Mbps. I've already asked BT to resolve the issue but nothing has happened this is why I'm leaving. Can I claim back for the speeds I was promised but never received?

Post hub stats. If hh6 then advanced settings then technical log information
did you report a fault to 151?
Is there any noise on your phone line. Dial 17070 option 2 should be silent and best with corded phone
Can you post your hub stats
Looking at the checker results I cannot see how you've got a 50Mb guaranteed minimum. Still waiting for hub stats.
This is a list of your BT Smart Hub settings and current statistics.

From the checker results it looks as though either DLM has banded the line at 40M or it has been mis-provisioned.
Posted before stats shown, stats confirm supposition.
Connection time only 5hrs was that manual reset or hub dropping connection
if you are having problems with your hub groping internet connection then looks like as @licquorice suggested that DLM has put you in a banded profile to try and stabilise your connection
