[Resolved]  Idea Cellular — Mobile Service Disconnection Problem

I had a mobile number [protected] issued from Idea Cellular, Hyderabad. I wanted to discontinue the services due to some of my personal reasons. I approached their Customer Care Centre in Fateh Maidan Road, Hyderabad with this request on 8th 10A.M. I deposited whatever outstanding was told to me needs to be cleared for going ahead with discontinuation. It was Rs 699/- which I deposited. I was told that it will be deactivated in 12 hrs of time. Even after I moved out of the city I found that the services have not been discontinued(althogh I didnot used that SIM card). I sent a mail to their customer care for this irregularity. They acknowledged and deactivated on 12th (day I sent email to customer care). Now they are saying that I will have to pay the outstanding pro-rata rental till 12th Apr. Why should I be paying for the mistakes done by IDEA customer care ? Which mobile service in the world takes 5 days to deactivate mobile service. It is because that I had authorized IDEA to charge outstanding on my credit card they can change anything illegal to me ? I want myself to be cleared of any dues and no charges be debited from my credit card.
