Hi Iowmancs. I'm sorry to hear you are having a problem processing your order. We do see this often enough as we are a Canadian company and a lot of credit cards have a good security system in place to flag any orders coming from outside the country. This is simply so your bank/credit card can confirm it is you. All you have to do is call the number on the back of your card and confirm it is in fact you trying to order through King Brand Healthcare. They will see the failed attempt and just need confirmation from you. They will then open the security hold and you will be able to process your order.
I know this can be an inconvenience, but for security reasons, it is a good measure from them to protect your card and your finances.
Please let us know if we can be of any further assistance.
Kindest regards,
Amber
