Unfortunately there is nothing we can do here to help with your problem. What I recommend doing is changing your password via a PC so whoever now has your PS4 cannot use your account and purchase games. More info on doing that here:
You may also want to deactivate that PS4 as well to ensure the thieves cannot use the content:. More info here.
Hope this helps.
My PS4 almost got stolen, i found it on the ground right near my door, the door was also open all night. There was foot steps on the snow. Don't know why they didn't take it, and just left it there on the ground.
That's why i set up an alarm system in my home, my German Shepard is good help too. I also keep my shotgun handy too.
I know that you can in fact that there is something you can do Sony. And I also know that you neglect to on purpose. If i stole a console from your factory tell me what you would do? Then tell me what you do when the police files a subpoena for the information needed to track down a console through your own channel even.
Recently my PS4 was also stolen. As former CSI for military I wasn't to upset since I know how easy it is to track down. I have the S/N and MAC address of the console which is all that is needed to find it.. I filed a police report and then requested a subpoena for the IP address connected to the MAC address through the Sony channels that are provided to the police force. Now Sony should be replying back to the detective with the IP that is the PS4 is connected to so that we can then subpoena the internet provider for the physical address.
But, guess what part of that breaks down. Yeah the part where Sony does it's part. And as I was told by the detective and confirmed through research online is that after submitting the subpoena that Sony just falls off the face of the earth. Is it because you know that we will just mindlessly go pick up another system? Rather have two systems sold than help recover one and make a happy customer? This is too bad. In my house there are three Sony TVs, three PS3s, two Sony phones with two more on preorder, some Sony cameras, well one less since one of those got stolen too, and God knows how much more money thrown your way.
Before anyone states that I do not know if the System has been connected to the net or not, I do. I waited to change my account password until I I saw my name go online and for some account activity to take place. I did change my CC info to a one that would not work. After my account went active again then I changed my password. All Sony needs to do is give the police the IP address that that console connected to network from and then the Police can finish thier job in getting it back.
