My biggest loot was when there was referral program by freecharge in which they gave Rs. 25 for each referral. I used some trick and got Rs 110000 in two months. I had lots of money to recharge so I contacted a recharge shop near my college and sold all the recharge amount for around 90000. I have no certain picture to proove my point but I have around 120 freecharge IDs . The recharge history can proove my point I think.
