I have been using internet from my airtel sim on my computer over an year or so. On 9th may, Rs.55 (approx.) was deducted from my account.

When I contacted customer care, they told me i was using airtel live even without any such settings!!!

Now my question is when i am connecting with dial up connecting, how can i choose between airtel live or mobile office?
I was already doing this over an year and this deduction suddenly happens on 9th may.
Is there any way that I get my money back else i m left with option to switch operator...
