There was scheme in an app to enter the code 90FC to get 100 percent cashback on a recharge of 50 at freecharge. that is why I started using this site but nothing like this happened. they said the money would come back within a day but it has been a month and the money has not come back.freecharge is like any other online recharge site like paytm. it has no special features as such.
I also recharged with 100 rupees talktime later. the recharge was done but on the sixth day all of the talktime money got vanished from the mobile and I was very careful about hanging up the call and not using mobile data. I have not used freecharge ever since
