I have purchased simcard from Ananda Cell city situated at Rajendra Prasad Road, Chrompet, Chennai 600 044. My cell number is 9003288427. Within a month my cell number is not working. When I contacted the airtel network centre, I was informed that my sim card has got damaged and I have to pay Rs.25/- towards replaclement of the sim card.
