Tataindicom walky
Not returning the security after disconnection

I took the connection of tataindicom walky last year. After 2 months I closed this connection. I was waiting for my security which i deposited at the time of taking connection. I talked to them and they said there are some pending bills . please clear these bills and in 30 to 45 days you will get your security back. So i cleared my pending bill. I deposited the bill at 7 sep 2007 and now more than 2 months have spent. but they are not listen to me. they are not responding me. pls. help me.

yours faithfully
