Vodafone India — wrongful balance deduction

My vodafone mobile number is [protected]. Current active plan on my mobile number is unlimited calls+1gb data for 84 days. After i activated this plan, my balance was deducted many times and finally balance became zero. After that an amount of rs. 3 was deducted from zero balance, now my current balance is minus 3 rs. There can not be any deduction for call, sms or data because my number has free calls, sms and data since past 60 days. So i want reasons for the deduction from my balance and i also want the minus amount to be removed from my balance.
As per trai regulation mobile operators are not allowed wrongful balance deductions. If my issue is not resolved asap, i will register a complaint with trai.
