Wrong Balance Deduction

Location/place: Pune

Name of company/service: Reliance GSM

On 26th or 25 th May, 2011 reliance telecom cut my balance of around Rs. 30. My balance was 65 and after deducting the balance it was Rs 35. I called at call center. Their executive himslf said that the outbound officers have activated some services or some packs by themselves without my permission and cut the balance.

I want my balamnce back because this company has done the same thing many times before.
