App does not work – Tweet Sponge Pro- Who UnFollow Review

I downloaded the free app and in order to immediately unfollow people you have to purchase the ad free version. I did this and the ad free version DOES NOT WORK. When you open it it shows a button that you cannot click to log into Twitter and that is it?????? Do not buy this app. I want my fckn money back.
