It's just the generic email that is sent when they've "escalated" your case. Absolutely nothing will come of it. Luckily! It used to be that the "escalations" actually delayed decisions on cases!
That may still be true.
While my application was going through, I was warned that escalating was a bad move unless you could prove compassionate grounds. That you should only go down that route if you have been waiting a *really* long time (by that I assume 70, 80, 90 days plus) and then only go through your MP.
I'm speculating here, but it could be that, if you do escalate, your application is taken out of the queue while someone assesses whether there is a justifiable reason for you to queue-jump. And, if they decide that there is not, they put your application right back again - so if you were number 100 in line before, they put you back at position 100. Of course, in the time taken to consider your escalation, a whole load of other apps have just shot right past you.
