Balance deduction by Fraud

YESTERDAY MY AIRTEL MAIN MOBILE BALANCE GOT DEDUCTED FOR RS.128. I CALLED AIRTEL AND THEY TOLD ME THAT I USED DATA PLAN. THEY ALWAYS TELL EVERYONE THE SAME THING THAT THEY USED DATA PLAN. I ALREADY HAVE DATA PLAN RECHARGE FOR DATA INTERNET. I HAVE 2 WIFI CONNECTIONS AND I USE WIFI , I DO NOT USE DATA PLAN. AIRTEL IS NOT READY TO REFUND THE MONEY AND BLAMING ME ASSUMING THAT CUSTOMER IS TELLING LIE. IT LOOKS THAT IT IS THE HABIT OF AIRTEL TO SCAM DEDUCT THE BALANCE FROM CUSTOMER MOBILE. I HAVE TAKEN THE NODAL OFFICE DETAILS AND I WILL COMPLAINT THERE AND ALSO IN TRAI.
I ALSO GOT CALL FROM AIRTEL YESTERDAY NOON TO SELL SOME PLAN BUT I DENIED AND THIS HAPPENS TODAY. AIRTEL HAS VERY BAD HISTORY OF DEDUCTING BALANCE AND DOING SCAMS.
