I was charged in playdamic golf clash with out successful purchase

How was it not 'successful' ? Do you mean you bought something but didn't receive it ? If you do, have you contacted the developer ? If you have, and if they can't or won't help, contact iTunes Support : http://reportaproblem.apple.com

Or : http://www.apple.com/support/itunes/ww (click on your country's flag, the country where you live, and which is therefore the country on the account ; click on Contact Support towards the top right ; click on Get Help under 'Talk To Us’)
