I have an old PSN ID linked to my bungie.net account, in anticipation for the release of destiny I decided to start fresh and make a new PSN ID. All went well until I tried to link my new PSN ID to my account on this site. I unlinked the old ID, then clicked link to play station network, and all it would do is link to the old ID. I have done this many many times and am beginning to loose hope. If anyone can help me please let me know. Thank you.
By your description, it sounds to me like you already have an alternate sign-in method, and are familiar with the linking/unlinking procedure (please correct me if I'm wrong). Perhaps your best bet might be to delete your cookies and clear your cache, if you haven't tried that already.
