In app purchase rip off

I bought this app and its very entertaining but when I purchased some coins and unlocked British celebrities category, it let me use it once and then locked it again plus each time you want to use your newly purchased category you must shuffle the other ones at a cost of more coins just to play what you have ultimately paid for once all ready, beware its a rip off.
Also the games categorys do not accommodate British culture, dont buy it until its properly finished.
