Hinduja Global Solutions — Related to fnf process of a employee

I am the employee of your organisation.
I resign the job on 15th december 2016 with a proper resignation letter.
But till now i does get my fnf, i got salary but there is more than 50% of deduction in it.
They are not able to provide me experience letter in the past 6 months.
I am call to the mam who is doing fnf n sepration process, she told me that come to the office i will complete fnf process, she told me this in march.
After that i goes to the office 5 times but still i m not able to get any fnf statement, experience letter and they does not tell me about the deduction.
I am furstated now because i m suffering from all this nonsense from the last 4 months and still they are not providing any document.
Now the office going to shift to the new place, that place is 15 km far away from my house n i m not able to go there.
By there delay in the process i m not able to doing job because i new hiring they want a experience letter for higher package, i m capable for the higher package but not able to do any thing
Pls look in the matter do as needed.
This is worst experience for me.
