According to some posts on Alla it seems some banks either won't allow you to use C&B while others warn customers they're 'shady' .. whether you believe those people posting that is another matter .. and links to web sites listing problems with C&B have also been posted.

They're also rated F at BBB apparently. Plenty of posts around describing problems people have had in other MMO forums too, such as Lord of The Rings: Online, Turbine have been dealing with C&B for some time now.
