I came to knew about the Wham Application through an advertisement on a Website.This application claims that It will provide gift cards on Exchange for points called as Whams. We can earn these points by clicking on the ads shown there in the app of various sponsors.I also earned about 3000 points on this Application but When I decided to redeem them in the App then It always shows- "Out of Stock". It’s been 3 months and still the 3000 points are unused.Their support never responds on their given WhatsApp number.So I would recommend to don’t use this app as they are providing wrong information to the customers.
