There are numerous reasons why your transaction did not go through. For starters, you should check your balance and see if you have not gone over your credit limits. After all, you cannot deposit money if there is nothing that you can deposit. Second, see what your bank’s policy towards online gambling is. There are several banks and financial institutions that have taken a stance against online casinos and similar websites.
In this case, you will have to use a different card or, alternatively, utilise another payment method. While this is not an ideal solution, there is nothing to be done in this case. Finally, see if you have entered all of the details correctly as there is always the possibility that you have made a mistake somewhere. These are the most common reasons why a transaction would not go through. For anything else, contact the online casino’s support staff and your bank for further clarification.
