Freecharge.in is making people a real fool because they are giving discounts but it is not useful at all.in their terms and conditions they clearly defines this offer is not valid for airtel users.if they want to give then why they are not including airtel users.most of the people are using airtel around 65 percent in India uses airtel operator.then what would be the use of giving discounts to the remaining 35 percent of people.I won't really agree with this and I believe this is a real business tactics to catch a customer.
Better that not to give any discounts if you want to give then give commonly to all operators or else no need of any discounts!
Guys I won't recommend this app and better you can try paytm and other app.
