Airtel — balance deducted from account for unknown reason

Address:

676122

My name is Muhammed Mubaris T and my airtel mobile number is [protected].

Today[protected] i came to know my account balance is reduced to Rs 3.58 from around 12( last time when i checked my balance. Since I'm a unlimited plan user, there is no reason for my balanced to be deducted. So I contacted Airtel customer care agents and enquired about the issue, they replied that a "Daily Voice Pack " of Rs. 3 was activated in my number on[protected]. I'am a type o[censored]ser who don't use daily pack and use montly packs. I did not get any sms related to this service too. So i concluded that i was not activated from my side. I would have known that because i'm a budget user and always conscious about usage and charges. The customer care agents transferred the call to senior agents and they said they have no options for the refund. I don't know how my amount i have loss from this. So I'am registering complaint against Airtel for deceiving me and tricking my account balance. I need full refund or i'll go to file compliant to court.
