I moved this to My Account Online as the most appropriate spot for it.
The payment pages are secure even though they don't employ VBV and similar.
You could speak to Customer Service and complain about that directly to them as they only have access to it.
&/or you could post a Product Suggestion:
Thank you for clarifying your view of what a secure payment is, but I am not talking about encryption. Verified by Visa makes sure the card holder is involved in the payment. It makes it much harder to use someone else's caard information at will. I'll make a suggestion as you proposed.
Then I would suggest it. I will also ask around here and let you know if I hear anything.
