My application has taken more than two years

My application has taken more than two years. MP has not got us anywhere.

Any idea what I can do?

See this thread with some pointer of how to chase UKVI.

Not sure if this is the sole reason due to redacted sections in my SARU
However, my application languished for 10 months after having chased myself, and by MP
They left a note in the case that I did not provide specific dates of address history, when the application only asked for months and dates
They waited another 2 months before a note saying they are asking for specific dates, then I received the email after 2-3 weeks
When I asked the MP to chase, they seem to have acted on the information requested after 3 months and I have finally got it sorted approx 6 months from when they decided to ask for more information
It's maddening
