Airtel — Recharge On deleted number

Address:

Maharashtra

Hi,

I had bought an Airtel 3G dongle few months back with data card number [protected].
I used it continuously for 4-5 month with monthly recharge of 750 rs. But in last 2-3 months i did not make any recharge on it. And when again on 22 July2012 I recharged it with 950 rs unlimited internet plan, It got successful and money deducted from retailer account. But there was no connection in my dongle.
I called to customer care and they told me that my datacard has been deleted.
I don't understand how my number get deleted and then how my recharge got successful.
And where my money went?

When I went to airtel relationship center they behaved very rudely and told me that I have to forget about it and will not be getting any money refund from airtel.
This is very surprizing, I was thinking airtel is india's top telecom company.

Please let me know if I can get my money back since I had no information about this number deletion policy.

Hoping for help.....

Thanks,
Anil Gupta
