Very unhappy – Sing Along Christmas Carols Review

Bought the app and it worked ok with the few free songs. I bought the additional song pack, and now it won’t play—no sound! I tried everything, then deleted it and reloaded, and now I don’t have the 10 extra songs I paid for!! I emailed the developers and have heard nothing. Also bought their piano songs and the same thing happened!!
