So yes I signed up last night and so far I love it.

However, I've got an issue with the billing. I put my credit card in to get started, but want to switch to my debit card, as paying subscriptions by credit card is insane. It says you can use a debit card issued by Mastercard or Visa, and I have a Maestro, issued by MC.

However when I put the card details in, it says this is not a correct card number? It's the correct number but it's not working.

Any help? I tried contacting them, but the guy's response bore no resemembalance to my question whatsoever
