Ok, now I am really annoyed! It is a VISA issue 100% but they have absolutely no dedicated team or contact for Apple Pay and are refusing to assist me at all. They have bounced me back to HSBC who are not at fault, and they proceed to bounce me to Apple, who are not at fault. The problem with having unaccountable massive organisations dealing with this process is that when something goes wrong no-one can help you!! GRR
