When a payment method cannot be verified online whilst placing an order, this lack of verification is not influenced by CLUSE, but due to the payment method or bank. There can be multiple safety reasons our payment partners reject an online payment (usually via credit card). We kindly advise you to create a Paypal account which is a secure method of payment or try another payment account when placing the order. In case of a credit card payment, you can also contact your credit card company and request authorisation.
