Facebook complaint: My Personal facebook account disabled

I have changed my mobile number and since i forgot my password to login to facebook, i used forgot password option and it says 6 digit code sent to mobile number when i did not registered any mobile with facebook and there is no option to send 6 digit code to gmail. I have tried other options and suddenly it says account disabled and i have 30 days time to appeal or request review. When i tried to appeal, it showing again some error message, and iam fedup of trying all options. What is the point of Facebook being such a big company and harrasing its customers like this. Iam in very urgent need of my Facebook account as i have all my medical records data in my Facebook account and its very urgent as i need to get my surgery done in few days.
On first hand why the account is disabled ? Iam not really not sure what did i do to not follow community standards of Facebook. Really its a pathetic thing of Facebook and iam struggling from last 5 days to get back to my Facebook account.
I even sent many emails but still no response and even told them iam ready to provide all my identity proofs given by government of India to prove my identity.
Please help me to get access to my Facebook account ASAP, as i need to talk to my contacts regarding my surgery planned in next week.
