MNP service idea is the worst of its kind. If you have taken MNP and if lost your card accidentally then thats it that will be the end of your number yo will never be able to use it again. I lost my sim 3 weeks back I still didnt got the duplicate number from them till date. and believe me I have been calling them 3 times every day and going to the show rooms almost everyday.
they dont keep the stock of MNP cards with them in the show room. others at customer care have no idea about this. the only place you will get it is at Nampally
the customer care people have no idea what going on in the idea show rooms there is no link at all. so if ask something by calling customer care they will simply tell go to customer care and ask them.
