If it stays unconfirmed for a day or 2 it'll go back to the wallet you sent it from. Don't worry. If it does get confirmed, 5dimes will have it and you can contact them about it.
5dimes did BS you a bit though as they cannot cancel the incoming transaction. They can only cancel the "deposit" from their end so not add the money into your account, but they have no say over the actual transaction of the coins.
received my confirmation after 6 days. the bitcoins went up 7% from the time of deposit to confirmation. would i be entitled to the price increase as i noticed i only received the original deposit amount?. i guess i wouldnt be bitching if the price went down 7%
