Ovocasino

Good evening..
I have a small problem.
I saw this page on the internet ovocasino.
There was also advertised with 8 euros.
Well tried it right away.
So I set up an account.
Apparently luck was on my side
Because I turned the 8 euro bonus into 170 euros.
After a while I had a turnover of 320 euros.
And only had 7 euros left on it.
Didn't think anything of it and played on the 70 cent tray.
Free spins 53 euros.
Put up 90 cents on 10 lines.
And got 491 euros.
Well in the end I had 600.96 on it.
I click withdraw and started entering my account details.
And now comes the stupid thing.
I have an autofill function in my cell phone that fills out the registration automatically.
Since a known time has registered with my cell phone.
Was his inside too.
And because I wasn't paying attention to the bowl, I clicked on his instead of mine.
Now his name was there.
And it couldn't be changed either.
I no longer have contact with my friend.
My question is can I get in legal trouble?
I don't really care about the money.
I haven't paid anything.
But would be stupid if I get an ad for it?
Hope you could help me.
Thank you..
Tried to log in to the account yesterday but it has been disabled.
