感到无语 So Disappointed – 6000 Words - Learn English Language for Free Review

I try the elementary level which is the free version. I thought it's good and then I see the highest level have the discount that only need $12 . I paid for the $12 to unlock the words but the app just stocked in the download step?! I tried to delete the app and downloaded it once again. But it’s doesn’t work!!!? I’m so disappointed with this app???
