For all those who are waiting for OVER 6 months and have failed to get a decision even after contacting HO first, MP intervention.
I would suggest to make an official complaint to HO especially if you have compelling circumstances. Mention the reasons how the delay has impacted your life, with evidence where appropriate.
Complaints are handled by a different department and puts lot of pressure to make a decision quick.
Obviously, you are well within your rights to make a complaint if HO has taken unnecessary time which is impacting aspects of your daily life and mental health.
PS: Send via post with recorded delivery.
