I tried doing that several times, I made sure there are more than enough funds in the card, yet I still got 601. I also made sure the problem isn't on my end.

I will try doing the chat support now and I hope it will work...

Try using UltimatePay with your CC to add Crysta if its an option.

If you are a service member stationed overseas and on NA servers, you will likely have problems buying Crysta even through Ultimate Pay. I did, I am still sitting with $75 of unused cards because they wouldn't process. If you purchase a game card and it doesn't go through, try calling Ultimate Pay, they can usually get it through for you.
