Double deductiom

Dear Sir,

I've purchased a game from apple store by my iphone and when i tried to download it to my ipad I received a message from my bank showing double deduction.

First one was on Dec, 21 and the second was on Dec. 23

1- (A trxn on your ADIB Covered Card 4713**5489 at APPLE ITUNES STORE-AED in ITUNES.COM, Luxembourg on 21/12/13 21:11 for AED, 17.99 is approved.)

Please correct this error.

Regards

Adel
