There are various reasons why fund transfer to your betting account using a credit card won't push through, such as the bank does not allow a transaction to and from the gambling sites. Prior to using your credit card when funding your online betting account, you have to make sure you check the rule and regulations of your locality. Some of the possible reasons for issues using credit cards in funding your betting account include the following -Your credit card is not allowed or blocked for making online payments. If this is the case, you have to contact your bank to remove the limit. -Your credit balance is way lower than you are trying to charge to your card. Before making payment to the online betting site, you have to check your available balance. Always keep in mind to be mindful when gambling. You only gamble what you can afford to lose. -There could be some technical glitch at the end of the betting site or on your end. You might want to check your end for any errors, be it internet connectivity issues, typos, or the likes.
