Hi there and welcome
Sorry but due to privacy policies the information would never be given out. But, there is not real information to give if this was not the case.
The only thing that's recorded is the IP address of the provider of the person who hacked the account, then you would need to get the information from that internet provider to get specific details. Both of these require court orders and even then they will fight it.
What I advise you to do is enable 2 step verification on your account. When you do this, unless they have physical access to your Cell phone, it will not be possible for them to hack your account. To enable this you can follow the instructions here
This, along with a strong password, will stop further access to your account again.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
