Home office verifications

Hello,

I am a student studying from sept. 2020. I applied for finance under a long residency. My application has been rejected to insufficient evidence. I have been gathering evidence from 2004 till the present. It has been a real challenge and although I was able to gather most of it, I missed out 10months in 2008. I did however provide acceptable evidence for January and October 2008. But student finance wants me to cover the period in between. The only other evidence I have is from the Home Office. However, the home office does not provide original copy letters. Student finance is aware of this...

What can I do? Any advice? I have provided copy letters from the home office and asked student finance, through an appeal, to contact the home office to carry out verifications checks for that evidence. As I have not heard anything, I am wondering is this something they do? Any idea whether my application stands a chance of success?
