Sony is the fucking worse to get help from, there was time when some dick snot fucker did something so bad that they had to do a mass IP ban on IP's to get rid of them, when I called I was told that my account was in perfect standing, so I asked for MY OWN IP ADDRESS to get unbanned, but they stuck with "Just phone your ISP and tell them to assign you a new IP Address", my ISP at the time was the kind of luddites that still thought camera's steal your soul, so they wouldn't do it. I had to go into the modem/router and fuck around to get a new IP Address. I was completely locked out of ALL OF MY PSN purchases, the Store would just give me an error on my PS4 and my PC. FUCK SONY SUPPORT. I did NOT have any malware that was making a zombie attack or any other issue on MY OWN NETWORK or ANY PC/device connected to it.
TL;DR: Sony support left me out to dry and 100% restricted access to my account because my IP was in a mass IP BAN, Support fully acknowledged that my account was in perfect standing but would not UNBAN MY IP address, and made me figure it out on my own. FUCK SONY "SUPPORT".
I really hope you get help and reach a resolution, but it can't be said ENOUGH that Sony's "support" is FUCKING TRASH.
