I'm with Darico, I've spent the last 3 hours trying to get any of the available payment methods to work and none do. I contact customer support several days ago and never got a response, but when I looked up the support ticket it had already been closed out and they claimed to have sent an email to my registered address (which is true, if they meant only the generic auto-response "hey we got that you contacted us, someone should be with you within 2 business days" message <.< ).
Error 601 or 401 no matter what I try, and today I tried contacting customer support but the field to put in your user ID now limits you to 8 characters, and mine is 10 characters long! Chat and Phone support are also unavailable before completing the form, which you can't do without providing a valid user ID, which they have now made impossible! DAFUQ menz ;-;

Square needs to hurry up and take my money so I can get back to relaxing and playing the game! >.<
