You can hire some hackers from the dark net. Or you should be a pro hacker to get into their server to find ur Account IP address and change the informations like an Admin -
Yea, it's kinda hard, i mean if your a professional hacker of course you can do ahaha, i mean you need to hack the database so for you i guess it's kinda hard ahahah
Yes, it is possible - however you'd have to get some experience in DLL injection / DB interception. There are plenty of people on the internet who are capable of achieving this .. I could perhaps help you as well.
