the vodafone guy clearly said that they do not get any update on prepaid numbers. they do get data on postpaid ones.
I think he's lying. Even operators like Uninor and Idea have good tracking systems in place to check present portability status of prepaid as well as postpaid nos. I experienced Idea port-in procedure recently.
Actually Sushubh when u applied for porting to VF, you should have got some message with Complaint number as you are saying that you dint get any... Even when i ported other Docomo Number to Vodafone.. I got a message then also your complaint #SR has been registered and it will solved by xx/xx/2011
So i am sure Airtel did not register a PORT OUT request .. This is unfair practice by Airtel.. Chor Saale.. Will be kicked out soon out of india..
