Anyone else have trouble with buying shiz on the PSN these days? We were going to go premium, but I can't add any funds to my wallet despite entering and re-entering details of two different valid credit cards.
I had this problem too.
I tried many different cards and accounts, all to no avail. From my 2 days of scouring forums and trying countless unsuccessful ideas such as making sure every detail was typed exactly the same as on my bank card, making sure my billing address was entered in the exact same way as it was on my bank statement, and turning on the option that allows you to automatically add funds to your wallet if empty when purchasing....the only thing I could find left that made any sense was a suggestion that I had somehow been locked out of using a bank card to purchase items from the PS Store. Apparently the ban is for 48 hrs and starts from the last time you tried to use a card to add funds (so don't try at 46 or 47 hrs or else you'll have to wait the full 48 hrs again). A few people replied to the thread saying that this worked for them, a few said it didn't, I went to the shop and bought one of those pre-paid PS card things instead, which worked, and haven't tried to purchase from there with a card since.
I successfully bought something from the PS Store only a few days before this instance and I didn't change a thing when attempting to make my last purchase so I have no idea what it could be or how I could have possibly been locked out, but I think besides calling Sony support (which didn't seem to be too helpful for most) your only options are to wait the 48 hrs or buy a pre-paid card. You could also try adding funds through their official website (I think it's the soe.com one?), but that didn't work for me.
