Arbitrary and unfair application of group Self-Exclusion policy

I opened up a account with King casino after checking on ask gamblers to make sure they are not part of any casinos which I have played before and SE due to typically poor service (normally around the area of withdrawals) I checked and it came up as jupiter, I signed up and played.
I then recieved a message asking for KYC and AML which is the norm and sent them off,
I then recieved a email saying that I have already SE from a sister site, they wouldn't confirm which site or when and asked why I SE, I tried to contact the casino via chat and kept getting timed out and tried to contact via email via the links in their emails and non work support@ and care@ have all bounced back.

I recieved a email saying that I have now been SE from all their sites, I am under the impression when I SE from a site then it should also apply to all others and also marketing from the group should cease (this is the case with another group I SE from) . I have since sent emails and all have bounced back. King casino also state that I have now been SE due to responsible gambling, I do play at various stakes including high but I have full control of where, what and how much I play. I stated in a email that I SE from one of their group companies (aspers group) as I had no communication in terms of how a large withdrawal can be made and without any assistance I eventually played the balance away, losing the balance is part and parcel of gambling, you win some and lose some but my concern is when you contact customer services and they avoid you (quite similar to King at the moment)

I enrolled using my credentials of name, address, email and phone which are the same for all the casinos I play at, there was no covering up of any information.

I'm under the impression that if I falsified information then my deposit, any winnings would be forfeited / confiscated. As I used my credentials then I'm also under the impression that I shouldn't be able to sign up to any casino in the group, so therefore see there is a issue with their SE system, on that basis I'm under the impression that my bets would be void and a refund of deposits would be due.

I am unable to follow up with the casino as I'm now blocked and can't use the chat function (albeit it doesn't work) nor are any emails being recieved or replied to so ask that ask gamblers can assist
