To ensure your order is not declined when placing a new order we suggest the following: - Check the card details on your Sinomugs account to make sure the information is correct, e.g. the expiration date or balance in your account. - Make sure you enter the security code correctly - that's the three digit number on the back of your card. Your credit or debit card company may have declined your payment. If this is the case, you will have to discuss directly with the issuing card company to find out why as we have no access to this information. - As an alternate solution, you can try paying with a different card. If you've tried the options above and are still having problems, contact ourCustomer Care Teamwith as many details as you can about the issue - including any error messages you receive and we'll try to resolve it as soon as we can.
