Shriram Chits — Delay In Closure of My FD

I have submitted my request to closure of my FD which was marked as lien against my chit[protected]. My chit period for 50months is over and I cleared all my dues and there are no pendings. I submitted my request to shriram chits to do the closure of my FD and credit the proceeds to my linked account. As of now there is no response from the shriram chits. Please action this immediately and confirm once this is done.
