Well guys/galls, I just purchased a $20 network card from my local grocery store. After entering the code to redeem I recieved the same message, "Unable to add funds to wallet." I went back to the grocery store to see if maybe it wasn't activated. They of course said, "Its activated at the register." So I proceeded to call Sony and was connected with a helpful person who informed me that, "There is a known problem with certain Codes." A KNOWN problem. Her fix: She sent me an email with the subject being "Missing or Damaged Voucher Code" and asked that I follow the steps to RETURN the card virtually and recieve a new code. Those steps require you to take pictures of your reciept AND pictures of the front and back of the network card. Then you email those reciepts with a subject heading being that of your SERVICE RECORD number (this I recieved in the email the nice lady sent me). In possibly TWO to FOUR business days I will recieve confirmation of the BROKEN voucher code and recieve and email with a NEW UNBROKEN code.
I was unaware that I have to work to get something I already payed cash for. Now I wait. This is a pretty big problem on Sonys part and I have to say, I was very irritated by the time I finally uploaded and sent out all the pictures and info they need.
From now on, understand that you may buy a card that the code is BROKEN and have to wait 5 days and jump through 10 hoops. This is more than likely my last experience with this because I won't RISK it again.
After waiting the thirty minutes it seems , my error fixed itself. And to all those threads about slow internet downloads, in less than three hours- I've added the funds, downloaded and installed a 4gb game from the psn store.
Glad my deposit was authorized! Hope everyone else finds as simple a solution as myself... and their problem just fixes itself w/ patience.
Also Sony has reported failures w/ some of the codes, if you have a faulty one, they said you have to take a picture of your recipt and contact sonysupport, after they verify proof of purchase and the error they will send you a new code electornically.
