Reliance Communications — mobile number blocked

I am using reliance number. Two weeks ago they blocked all incoming and outgoing calls. I am not able to receive any calls from anyone. I made a top up of rs. 500 for three months unlimited calls. I used for 15 days only. After that they blocked my number. I am not able to connect customer care number. When i contacted a service center nearby, they told that they are going to close the network. Help me to get my recharge amount and my number.
