Same situation and card as me, don't think I can be bothered dealing with them anymore though. Contacted them first time around, no reply at all... few weeks later I tried again, got a response requesting that I reply to the e-mail with my details and the card details. Did that, no response.
Few weeks later I chased them up again (making sure to include all of the original correspondence I sent them including the details they requested), and today they've got back to me with additional requirements that they didn't mention before... specifically that I have to register, provide proof of purchase (from three years ago which is long gone), and then resupply them with all the details again.
I think I'm wasting my time going by other peoples' experiences in this thread. Tempted to just leave it and buy another card when I can afford it, especially if this is just the start of potentially more hassle.
