SKS Microfinance - Balance deducted through Fake SMS of internet pack activated

Dear Sir/Madam,
Before 3 or 4 months I find a sms on my vodafone number (9583397312) that, your internet pack has been activated with Rs.99/-. Now you can using unlimited browsing for 30 days. I used browsing for near about 10 to 15 minutes. But unfortunately the internet disconnected. When I checked my account, it was negative balance of (-350.20) rupeese in my main account. I wait for some days, but still my account not recovered. After some days I disconnect that sim card from my cell & used an another connection.
But from 1st January 2012 I am using that previous connection (9583397312) & on 2nd January I received two SMS from vodafone. That was (Dear Customer, your account has been adjusted to 0.01) & another was (Dear Customer, your account has been adjusted to 0.00). But still now my account is in -350.19 rupeese.
I am fully intrested to use this connection.
I am requesting you to adjust my account with rupeese 0.00. Therefore I could use this connection smoothly.
