Consumer Redressal

I used 2G internet service on my mobile on 29-Jan-2014 at 22.00 hrs and close my internet then my main balance was Rs. 45 appx. , next day on 30-Jan-2014 in morning at 09.00 hrs I saw that my main balance was Rs. 8.00 appx. and I use Internet for 2-3 minutes and I saw that my main balance only Rs. 5.00 appx. I call to customer care number and IDEA customer care executive told me that I used internet service in morning on 30-Jan-2014 that\'s why they have deducted my balance Rs. 35.00. But its a wrong deduction, I haven\'t used any internet service other than that only 2-3 minutes for which IDEA already deducted my 3.00 Rs. I haven\'t used any internet service for which my Rs. 35.00 app. deducted.
