Casino allowing opening new accounts on sister sites after been suspended, is this legal?

[KL9933]

I just realize that I been playing on a sister site after being banned from their site. 
Previously I had planersportsbet.com and after I got banned :

Your account has been suspended for security reasons. Please contact Customer Support at [email protected]

found nrg.bet I first recognised the platform was so similar but checked their license to see if was planetsportsbet.com

it only had rhinobet.com. Which I also had an account. Site is closed now. 
I went through verification process with exact same details including same email, same driving license used at planetsportbet.com 

the question is I was informed that I should never have able to open on sisters sites and carried on depositing. 
Do I have claim ? 
 

The head office for both of the site are the same just the license number are different. 
 

so please give advice much appreciated

Well the sister site operate on its own, if you were banned from one site, they cannot ban you in the entire group IMHO, but however casinos do what they see fit, especially if you won money. And not worth battling it out, especially if you havent lost money. Rather find another joint to play at.
