Last year my PSN account was hacked

Last year my PSN account was hacked and games were purchased under my account that I never purchased and the person that hacked my account made two other names under My Family Management and once I got my account back after contacting playstation, I did the two-step verification and everything was okay but I could never delete the two names from my family management.. I tried everything.. I downloaded the PlayStation app on my phone and on my console I tried to delete the names..but nothing works.. and I have called PlayStation many times nobody could ever seem to delete those two names that are under My Family Management... Does anybody know what I could do to fix this?
