[Resolved]  Airtel — Billing cycle

My number is[protected].

I had requested Airtel to change my billing cycle to the 1st of every month. To this, the only answer I keep getting is that this cannot be done as the cycle is "predetermined" and there is some "policy" because of which this cannot be changed. All appellate of Airtel keeps giving this message. How can this company call itself a national player if its systems and policies are not able to accommodate a simple request like this?
