Not sure tho, I don't want to tell someone my credit card info over phone in any case. Someone around you can be listening to you, or even worse, recording you.
Sure - in the UK a lot of companies don't offer any other way to pay them, or the way is a lot less convenient(you can pay with your card over the phone and have the order shipped today, or you can send us a cheque and we'll get to it in the next 3-4 weeks).
