Airtel — unnecessary balance cut after recharge of 84 days

Dear sir,

I had done recharge of 84 days a still 30 days before without completion of days balance is cutting in my account on daily basis. I had tried 198 customer care at least 10 days but it's boring lecture is started and not given call of customers care executive. I have afraid about this matters. So. I raise complain about this in consumer forum both indian and national. This us clearly cheating with customers. Its customer care not support for its customers.
