psn is seriously messed up.

ive used the same bank on psn for around 2 years.i just bought a psp go and downloaded a few games.when it came to downloading final fantasy 7 and metal gear solid, it started to say bank detail incorrect go to account management.why will it let me buy some games and not others. i have plenty of money in the bank but i really wanted those two.has anybody else found this. ive tried redoing my details and doing it on the psp itselg. i just don't understand it at all.

mabye adding a little more money will fix the glitch but before doing so try again and send sony an email or sumthin

tried it but stil not working.going to try technical suport.

If you go in and erase the payment method and then reenter the information the problem will most likely be rectified.
