Airtel — balance deduction by vas

Address:

Kolkata, West Bengal, 743135

Hi, this is sabita roychowdhury. As you can see i newly joined your network. On 22 dec my main balance was rs 22 approx.
Suddenly you guys activated a vas with my consent and deducted the entire balance. Then i recharged with rs 30 top up which gives approx rs 22 talktime. But again my main balance became rs 0.
Atlast today on 1st jan i have recharged with rs 20 top up. Till now my main balance is rs 16 but may it will be reduced to zero again.

Check my account thoroughly since 22 dec, refund the money deducted by you.
Otherwise i will have to port out.
