I've recently made a payment to bitinstant through ZipZap to receive my bitcoins to my bitcoin address. I've had 3 flawless transactions, but this time I haven't even received an email after my payment that notifies me of my recent transfer. However, I did receive the email from ZipZap saying that it would notify the merchant of my successful payment and to complete the order.

Although; I didn't save the orderID.

What now?
