[Resolved]  Airtel — Call Charge Trap

I am Linson thomas.. I am using Airtel sim since last 2 years. My mobile number is [protected]. My call charge was 75paisa to all local mobile phones. one day i call the offer enquiry number 51561. on that there was recorded message "Inorder to call all airtel numbers at 30 paisa /min i forced to join daily rental pack of Re.1. For the cancelation of that offer and goback to the previous plan all i need is to recharge with Rs.3.
I recharged for Rs.3 & my call rate changed to Rs.1/local call.
I called customer care but they replied "whenever you recharged with Rs.3, your plan will changed to general plan instead of your previous plan".
But the recorded message was "Inorder to go back to your previous plan you must recharge for Rs.3"
What i will do...
The recorded message was still there on the number 51561 for a long days...
What i will do to get my previous plan??
