I have been recharging on freecharge.in for past 5 years and I havent had issues with recharge. few times the coupon where not send on my mailing address. When it was launch they would send coupon on your mailing address for free. afterward they started charging Rs.10 for mailing. I still remember I once book movie tickets online with coupons from freecharge.in the movie tikcets for 2 cost me Rs.64 at R-mall Mulund.
