If you live in the United States an want a refund an Playstation support refuses to issue a refund this is what you must do an note this is only for the United States.
First reach out to support an document their response. Let them know that their updated refund policy states that they have the caveat that "if a game is faulty:
Link to USA refund policy
Next if they still refuse you must then contact your States Attorney General's office and file a consumer complaint against Playstation.
You should let them know all the errors you're having an link them playstations refund policy an how it mentions faulty games.
From their you play the waiting game an hope your Attorney General's Office fights for you as mine did.
I cannot guarantee that you will be successful however this is your only option in the United States without risking your account being banned.
I suggest you use professionalism an respect both with Playstation support and in all communication you have with anyone throughout this process.
I hope this helps some of you who want refunds an it helps to learn the laws for your respective territory.
Best of luck ~Cyb3rs34l
