I got no error(s) from Mog Station. My infos are the same as before, never changed. The weird thing is that my CC/bank account haven't been charged and yet I'm still able to log on and play as usual. I contacted SE rep about me unable to process through the payment and this is what the guy told me.

Agent : Okay there are a couple of reasons
Agent : could be that there are no funds, bank blocking transaction, billing address/name was not correct, you are at a different location than the billing address.
Agent : Unfortunately there is nothing i can do to lift that lock and you will have to wait 24 hours times the amount of tries.
You: everything is correct as the card is being used very often
You: and as I thought...I changed the payment method to my checking account and still nothing
