Is the application straightforward or did you or your wife receive a non Straightforward email?
Well I will briefly list the timeline. We did receive the email, but only after so many days.
Online Application: April 28th
Bio-Metrics: May 7th
Application Received Email: May 16th
Email to UKVI asking WTF: July 24th
Non-straight forward email: July 25th
Request for IHS payment for son: July 25th
Email from me confirming payment: July 26th
Email from UKVi saying it's been escalated: August 23rd
Email from UKVI saying payment received: August 27th
I'm currently at 76 BD and waiting. I can only gather from the above that they didn't do a thing to the application until they received the email inquiry (people say it's not related here; but the barrage of activity after 2.5 months of nothing seems too much of a coincidence).
In the mean time, I've been pursuing anything possible. The MP timeline is:
Email to MP: July 25th
Letter in Post from MP confirming they are checking: August 1st
Email to MP asking what happened (28 days past; 20 working): August 29th
Letter in Post from MP saying ABSOLUTELY NOTHING of worth: August 30th
Also, I pursued a complaint against UKVI for not treating the application as priority. That was submitted on August 23rd. I have the paperwork to complete the Parliamentary Ombudsman complaint now, will be emailing and asking the MP to sign tonight.
It may be absolutely useless, but I have to do something. For the 100K new words and rules they added to the immigration regs, they didn't make it more streamlined. This process is honestly a joke. It's like how Donald Trump does business, take a service and cash and not pay anyone back or perform service. When complaints come up he says 'sue me', knowing full well the other party doesn't have the power to do anything. UKVI is taking insane amounts of cash for performing a service which they are not performing, and citizens have no reasonable recourse to correct it.
Good luck with your application.
