Someone hacked my google drive and restricted me from viewing my own files. I have their user name, LaLa LaLa. How do I find out who that person is? No Email address beside it like usual.
It's not clear what you mean by "restricted me from viewing my own files" but in any case the first that you should do is to follow the instructions on Make your account more secure.
- Disable the file synchronization with your devices.
- Check your devices for malware
- Try to recover accesible versions of your files. For details checkout View activity & file versions
