Hiya,
Getting a denied visa is probably one of the worst feelings I have ever had in my life. It's this horrible helpless feeling. It happened to me twice. The first time we didn't fully comprehend the income requirements (I hadn't found UKY yet) and the refusal was warranted.
I do hope you've taken some time to be sad since you found out. Having a really good cry and railing about UKVI really helped me.
Alright. I have to ask, were ALL of the details discussed in your refusal letter incorrect? Or was it a mix of you and the person married in Pakistan? This is important. It will affect the content of your email to them.
Remember,
this mix up was not your fault. It lies entirely with the UKVI.
Basically, you know a mistake was made by the ECO in regards to your case/application. You do not know the outcome of your application, I would not mention anything about whether or not you were refused or denied since you don't actually know. You have righteous indignation on your side. Use it.
Be polite, firm and strong in how you write about your letter containing the wrong details. You know you are in the right, a mistake was made. No matter how upset you are, please remember there is no need for name calling. The person who made the mistake isn't likely to be the one to see your email. Mistakes like this do not happen regularly. They are human, they can make mistakes.
(politeness and understanding is always appreciated by those who are on the front line working with upset people)
What you need to do is send them an email explaining exactly what has happened, include all the pertinent details, your GWF number (i may be calling that the wrong thing, it's been awhile), etc. I would suggest including excerpts from your refusal letter (possibly a photo of it if it's legible when you take the photo) and photos taken of your actual wedding certificate. Referencing the attachment of the photos in your email. Also reference all of the incorrect information and providing them with the correct information. The more data/references you can use as proof, the better your claim.
They should have all of the documentation they need to verify what you are saying is correct. It depends on what they sent back to you. I know some people got the majority of what they sent in back from them (including the copies).
It may be a good idea for you OH to contact their MP sooner rather than later about this. Personally, I would try to contact UKVI myself first, waiting for the timeframe the autoresponder lists for an answer, then you can tell your MP that you've tried contacting them first and since UKVI hadn't responded you need their help. This shows you are trying to work within the proper framework. UK people like that.
Please realise that this will not guarantee you'll have an approval at the end. It should mean that someone else will go over your application.
And just as an FYI:
I was working with the UKVI in early January of 2014 when my denial came through that I was able to get switched to an approval. I was one of the last people to get an email that told me whether or not my visa was approved before it was posted to me. These are the exact steps I took.
I'm sorry this has happened as the stress is horrible and no one needs that in their life.
X-posted with Sirius The Administrative Review that Sirius has linked to is essentially what I asked for but was not available when I applied. I'd take a look at that as well, since it's pretty much exactly what I say to do in an email rather than through their 'official' channels.
