Once I received an notification fron from charge that on recharge of 500 you will get 20% cashback but I tried to recharge it but when I enter my atm number when it was loading to pay it said error try again and I again tried to recharge after all 2 times then I got recharge but I dint received the cash back when I searched for it said only one time per user but it was my first time when I was doing first time it said error but not recharge done and no amounted debited so from then I thought not use this site even not using of one time it said only one time per user.
