Consumer Redressal

I am an Airtel 4G LTE consumer in Kolkata West Bengal. My Device number is 8585814336 and account number is 1041626816. I am raising this concern with respect to irregularities that I have noticed in my account which suggests pilferage of internet data that is entitled to me on a monthly cycle. I have a monthly usage limit of 10GB of data and the billing cycle is on 11th of every month. Generally my average usage per day is around 0.xxx GB. On 23rd and 24of December my usage abnormally went up to 4.23 and 2.72 GB respectively. I raised two complaints thru Airtel customer service on Dec 25th and Dec 27th, complaint nos 54361731 and 54394868 respectively. They were closed without fixing my issue and notifying me. As a result of these two bulk usages my account balance shows used up beyond 10GB and my connection speed has reduced so much so that I cannot use the connection at all. When I reach out to Airtel customer Service they are telling me that they cannot help me before my next billing cycle as the usage details will be only visible then. Yet they closed my service requests and stopped my speed of internet service from now. Request your good self to take up this matter immediately as I feel that this is just not a problem with me as a consumer but problem with lot others who use this kind of service.
