I didn't like ClickandBuy very much, either. IIRC I used them to pay using credit card, and when I got a refund from the merchant, of course the money ended up in the CnB account. I almost forgot about the money and had to pay some stupid fee to get them to close the account and transfer the money to my bank account. Not more than a few Euros, but I still felt cheated and more than that, it was a hassle.
As I said they're similar to PayPal. ;)
