I provided the email, you claim you emailed it and it gave you a bounce back, I've emailed it, there's no such bounceback either automated because the mailbox is disabled or auto response from the mailbox.
"Tried that email address and it doesn't receive email.
I get this message when I try that email address:
Your message to
hideaki.nishino@sony.com couldn't be delivered.
I appreciate you reaching out to me, any information you require please ask."
I've emailed on your behalf, I will follow up when i get a response, in the mean time, if you're telling the truth, my suggestion would be to email, include your name, address, phone number, reinforce on Hideaki that you're a long standing customer, make him understand you have contacted large gaming communities like Neogaf, advise you are seeking legal counsel, say you are contacting the gaming media and mainstream media., if you want this resolved you have to put the work in, it shouldn't be like that, but it is.
Keep repeating or contacting first line support staff will get you no where.
