just tried to make a sim only purchase but when I get to screen for ‘1p’ and card verification I can enter all card details in the boxes except for the final two boxes asking for the month and year of issue for card, these two boxes refuse to allow details to be entered. As a consequence my Visa/debit payment is refused, having attempted several times to enter details, which I know to be correct my payment is repeatedly refused.
I can see From a recent post other people have the same problem.
It appears there may be a technical problem with verification page. Can you please advise on the problem?
