I have tried using so many wallet apps among them oxigen wallet is A-one.
Its the worst app I have ever used because I have seen very less cases in providing offers and discounts for recharges and purchases and I takes so much of time to complete one recharge and also it takes so much time to give cash back and once my I got an cash back for recharge and after some time the wallet is zero and then I tried to contact with the customer care but they very worst in giving feedback and so from then I decided to not recharge in it and I recommend not to use it.
