I registered on oxigen wallet once while it was promoting an offer of cashback on adding some money to wallet but as soon as I added, my problems began because there were many restrictions like cashback can not be use for shopping. I had tried many wallets till now but they do not restrict for using cashback on shopping but oxigen do. Also once if you have created your virtual card then even after cancellation of it, you will not able to get this money back to oxigen wallet and money will be stucked to RBL wallet then. There customer services are also very poor. When my money got stucked, I went to higher level customer team and they solved my issue but it was really very hard to get help from them. SO be careful while using Oxigen unless they improved thier services and thier habbit of applying restrictions to customers. There are many other wallet services which can be used instead of hanging your money with Oxigen.
