向itune申請退費後的回信

各位大大好！小弟因為搞錯id，而用了不同id登入itune後，下載了一個我以前下載過的軟體，因為和之前下載的id不同，所以是要收費的！也因此向itune申請退費，就像爬文後其他大大說的一樣，apple的效率很快，在一天之內就回覆我的申請了，不過“全是英文”，不曉得有沒有大大可以跟我說一下內容是什麼意思，原文如下：
After reviewing the information you provided, I went ahead and reversed the charge for the duplicate purchase, which I understand was unintentional. You will see a credit of $1.99, plus any applicable taxes, in three to five business days. If store credit was used for this purchase, you should see the credit post within three to five business days. If you still do not see your store credit, you will need to sign out of the iTunes Store and sign back in.

Please note that this is a one-time exception, as the iTunes Store Terms and Conditions state that all sales are final.

In the unlikely event that you receive a download error in the future, please remember that it is not necessary to repurchase items when downloads are interrupted, because the items should still be in your account, waiting to be downloaded.

可以幫我翻譯一下嗎？謝謝！
