I can feel your pain now you can make them work on ur file please find below some suggestions.
First collect some additional proof , whatsapp chat history, skype history, ur both photos with your daughter , old or new , Long form , B form, NICOP etc.
divide them in 2 parts,
Send 1 package by email to LVO Attention to NXR & also write Most Urgent In email Subject.
After 5 or 6 days
Send 1 package by email to LVO Attention to NXR & also write Most Urgent In email Subject.
They will take 28 days to add all additional documents in your file ( means they will open your file 2 time to work on which is required the most now)
If you need to make things more speedy so you can send them Package 1 by courier, it will take 4 to 6 days to open & update ur file, little costly but again they have to open your file to add documents & this is what actually required now.
May be NXR is on leave some other officer is assigned to complete his task so again there is a chance that your file is opened & considered for completion.
After 5 to 6 days, send 2nd package by courier to make them work on your file.
Find people who are poor & u can offer lunch or dinner, don't offer money, buy food for them & after that, pray to God, that he helps you.
You can ignore all above suggestion, if you don't like.
don't consider my time line as i am 2012 applicant after completing every thing in Jan 2014 in ISB my file was transferred to London so i had to wait alot.
