If your sweeps coins are not credited after a purchase, the first step is to check your transaction history for any confirmation of the transaction. Make sure the payment method you used shows a successful transaction. If the problem persists, contact the customer support team of the sweepstakes casino, providing them with transaction details like date, time, and amount. Most platforms have dedicated support for handling such issues. Additionally, ensure your account information is accurate, as mismatches can sometimes cause delays in crediting your coins.
