Airtel Postpaid — Billing for the number which is deactivated

Hi

I logged a compliant in airtel customer care for billing beyond the usage ect. For the mobile number[protected] every month Rs 30 had been charged against SMS which was not used ) I was given assurance that they will pass a waver against that but it did not happen. (they passed waver of Rs.250 after I sent mail for deactivation )

I sent mail for deactivation of the mobile number[protected] on 3rd sep 09 (billing period was 20th to 19th every month )but still bills was keep on coming (till 21st of November) I called up airtel customer care and informed about this couple of time to customer care executives in the month of September and October it did not get resolved, finally on 29th oct 09 spoke to Mr. Manjunath manager customer care and updated him, even after that I received bill for the same on 26th November 09, again I called airtel customer care and updated complete issue to another manager he assured me that waver will be passed for 2 months ie., oct 09 Rs.252.59 and nov 09 Rs.108 without fail since there is a mishap from earlier executives who handled it.

As a follow-up on 9th Dec 2009 I called up airtel customer care and spoke to Mr. Jitendra I found out that they are not passing any waver since there back end team said that waver has been passed on September month itself( referring to Rs.250 passed on September) and asked to send detail mail since he cannot help on this.

Kindly request you to pass Waver of Rs 360.59 = Rs 252.59 (Oct month bill )+ Rs 108 (Nov month bill)

Question :-

1. How can SMS being sent and charged Rs.30 when it was not in use ?
2. How can waver passed in September month for October and November month ?
