There are several reasons why a deposit may not have been successful. You need to use a unique ID provided by the casino in the e-transfer message field. This unique ID cannot be used for any other transactions. It also needs to be correct, so Gigadat recommends copy and pasting it instead of retyping it. You need to start the transaction at the casino, before you send in an e-transfer, and make sure that the amount you send and the amount you stated on the casino site is the same. When you start a deposit transaction, you need to complete it within 24 hours, or the transaction will expire, and the process needs to start again.
