That is what I asked. My husband doesn't think it will do any good to ask. He is also afraid us being persistent will end with getting refused. I look at it like I've dropped a ton of money on two applications and the least I should get is an answer as to the delay. But I suppose that is just me being impatient.
I emailed back and forth with my husband's MP's assistant about 15 times AND my husband did AND he called. He was also worried about being pushy with the MP, but honestly, this is the only person who has direct contact with UKVI and the only person who can apply any pressure (although it's probably the smallest amount of pressure).
We really ramped up our efforts with the MP after UKVI said that they has never received my extra documents that I emailed to them. Our MP finally agreed to call and got the specific date that they marked my documents as received (which was 9 days after I emailed them) and I think it helped apply some pressure.
It sucks. It really really does. I hate that you guys aren't getting any more information, but the persistence should help pay off or at the very minimum get you a little bit more info.
