Reliance Communications — Pending Broadband Connection

My Name is Asha Sisodiya & I'm running a small web development firm in Bhopal (M.P).
I booked a Reliance Internet Broadband Connection on May 25th 2008, We made the payment of Rs.500/- as the installation charge. We got a phone But the internet installation is still pending. We made several calls to the Reliance Customer Care but Customer care is only taking complaints but not taking any action. Reliance has already withdrawn Rs 500 from our account for installation without starting the connection. Now when I'm asking for my money they are saying that we'll be refund in 1 or 2 months (or never).
it's a fraud!. It's the worst experience for me and same experience to so many people (browse this forum & you'll see the similar problems).
