Just got off the phone with customer support. No help whatsoever.

The representative said he "thinks" 401 is due to a credit card being used to many times and/or flagged for suspicious use -- I use my credit card frequently and have no issues with any other vendors or services, including FINAL FANTASY XI! -- and I got this on my first try, so that doesn't make sense. He also "thinks" 601 is due to errors on the bank's side, i.e. rejecting the transaction for some reason. Again, this makes no sense and I use the same card for XI.

According to him, either or both of these errors can place a block for as long as 24 hours. Repeated tries -- which, admittedly, I did -- can prolong the block. He doesn't know for how long.

He suggested I try again in "a few hours," which, if the block is for 24 hours or more, also makes no sense.

I'm not trying to bash this representative, but he definitely either 1) did not know how to resolve this issue, or 2) did not have the authority to do so.

I asked whether the block(s) can be lifted, and he said no.

He also suggested I try Crysta. I'll try that now, and post a follow-up.
