It wouldn't be flagged at the time of registering and using the card. We've had this same issue over and over again at the forum and I don't recall ever reading a positive outcome! The casino will usually always refused a withdrawal if anyones card but the account holder has been used. As you can no longer play at an online casino with a credit card, PayPal might be a useful option to consider. The popular payment provider allows you to link your debit card or bank account directly to your PayPal account. From here, you can either fund your PayPal account before linking directly with your chosen online casino or opt to use PayPal as an intermediary. Initially, a £500 capped limit will be added to your account. However, after passing sufficient identity checks, you'll be able to fund your online casino experience freely. Just be aware that not all online bonuses will be redeemable using PayPal as your chosen deposit method.
