This BOI Star Rewardz has more tecnichal problems and many issiue’s and bad UI.The most popular problem is we can’t use over reward points and some time the rewards points will expires, so it will no use of earning reward points it is waste of using and rewards the rewards will expires, so you should use your reward points soon and some chance that you will lose your money without making your payment so use it carefully. when I redeemed my points but they didn’t send me my points even I contact them no use all.when I recharge the money dedicated but there is not recharged.some times it not even open and many more bugs in this app, It is totally look like a third party app.
