When I came to know that thus app gives rewards I was enthusiastic about this. Everyday is let you show 3 adds of which you get 10 whams each. Over all process is slow but lets assume its ok for now. Problem happens when anybody want to reedem their whams for gift cards. Wham customer service says they have limited gift cards. But it always get sold out less than 10 seconds. And according to them this problem happens to them who live outside of bangalore. So berofe downloading think again. I’ve collected 3000 whams already but never got a chance to reedem any card. 2months ago their rating was almost 4.2 or more but now its only 3.9 because of their service. I think im gonna unstill this app, becoz its nearly impossible to get any gift card.
