Airtel Prepaid SIM
SIM blocked permanently without verification

I purchased one sim for prepaid airtel connection and got it activated after depositing all the docs. next day i got it recharge for Rs 100. made copule of calls before I found that my SIM has been blocked

I did n't received any calls for verifiaction on my mobile. When I checked from customer care they told me that it has been permanently blocked due to verification failure. I asked them to give details of the person or call when verication was made they weere not able to provide. I didn't have mny missed calls either

kindly suggest what I do. I lost Rs 395 without any reason
