Vodafone India — post call notification

Address:

New Delhi, Delhi

I use a prepaid vodaphone sim in my phone. I want the post call notification to be disable (By that i mean, the message that pops up after my call sayin "your last call charges was xx. Xx and balance is yy. Yy".

I find this irritating and i think the customer should have the freedom to decide if he wants that notification or not.
I talked to cc but they expressed their inability. But i m not convinced. Pl help
