Transfer Ps4 credit to another account?

If I want to top up my credit, it works with my mother's credit card. That's why I asked her to top up my credit so I don't do anything wrong. She had noticed that we still have a credit card and has redeemed it on her account. I used to have a child account and she was able to transfer the money from her account to mine, but since I'm an adult and you can't change anything about the age at ps4, you can't make me a "child" again where you can give me money transmits. Does anyone have any other way of getting the credit from your account on mine?

No doesn't work.

So if you want to get a game from the credit, you can simply transfer your mother's account to your ps4, activate it as your primary account and buy and download the game via the account if the game is on the account (which is also on your ps4 you can play it on your account as long as your mother's account is activated as the primary account
