I can't insert my Credit card information. It keeps asking to check my bank. Any ideas on...

There could be an issue with the card or bank authorizing the use of the card. I would also double check to ensure all information is correctly inserted.

Only thing i can suggest to to keep any bank cards or credit card off your console

It was just a normal bank card but I got it set up so it can be used as a debit card but when I try to add the card details to my payment options it only gives me the choice of credit card or paypal, I tried putting the card details in under credit card
but it just keeps asking me to enter a valid card number, where/how do you do it? :S

The phone support also informed me that the account is in good standing and verified that this card was used in recent purchases. I have checked my credit card account and everything seems fine. My Paypal account is linked directly to my bank account and
for some reason that is being rejected too...

Really? That's just plain stealing! I have a better idea. I simply lie about my details since I won't ever give these thieves any of my bank account / credit card details. 800 points... hmpf!
