[Resolved]  Airtel - Prepaid SIM — Lost of Sim

I have a shop in Pune - Pimpri Chinchwad (Bhosri Area ), which was broken into ( robbed ).
Due to this incidence I lost my mobile and my LAPU sim which i was using for E- recharge for my customers. I had registered a F.I.R in local police station and handed a copy of the same to local dealer requesting him to give me another sim for E - recharging as the sim card lost during the theft had a balance of Rs 2000 in it.
It is more that one and half months since the incident happened and i still have not received the sim card. After repeated request to local agent and dealer, I have visited main brach office but again i was sent to dealer, after my all effirts i am still struggling, no one is able to tell me where should i go ?
Previouly the local agent convinced us that the sim be provided to us very soon. Then he gave us a new sim with new number saying that old sim number and transferring balance amount may take some time so you can use this new sim. But not the new one is still activated nor replacement for old one is given to us.
The dealer says that he doesn't have spare sim (Recharge sim -Lapu) and sending me on new addresses everyday for the same .
Now a officer in a main branch told me that after 45 days the sim gets blocked and the balance can not be transferred to any sim, ?
What does it means, will i have to forget about the balance amount left in old sim.
I dont know what to do ? To whom i should complain about ?
Please gude me.
Thank You.
