Karvy — complaining about my relieving letter and full & final

Hi,
Himani this side worked in a karvy stock broking company in delhi branch code - 86830 and had given resignation on 23rd of oct and serve notice period of 15 days so my reliving date was on 6th of nov but on 12th of nov i got mail for absconding for which i communicated with my seniors that i that was possible so there was a mis communication then i contacted hr and admin in delhi as well as contacted hr senior in hyderabad they say they will look after this but it was almost completed 6 months and got no response after so many follow up mails. Its such a bad experience that after this i am unemployed from last 6 months and still not getting any help from anyone.
