This thread has become very difficult to read through because of walls of text that are quoted by the OP. If the OP would refrain from quoting several long posts when making a reply, it would make it very easy on the eyes to process what is being stated. I cannot be the only one here that has a problem reading through this thread.
I guess I contributed a little for that difficulties, as my reply is usually long and detailed. When that got quoted and the quote got quoted...
sumimasen.
I would advise you to prepare a nice cup of coffee if you want to read
OP's thread on CG, as it's more... seven-course-meal-of-words-and-sentences. With his consecutive posts [that made the mediator gently informed him that it make things hard to understand], posts being made private, posts with links to screenshots, another consecutive posts, and here come the third meal.
Ehm, anyway, to answer your question in simple,
Just in order to understand the situation, I have two questions that I would appreciate answers to.
First, how much did the casino offer to settle the matter?
Second, how much does the OP want to settle the matter?
First, the casino is ready to settle for 508.72, which come from the total deposit from OP's third account. After several factors and input being considered, they bumped it to 600 as their final offer.
Second, OP asked for 10,000+ USD aside from that 508.72/600, under a reason that it was the amount he lost during his second account.
If I may give a better and more in-depth explanation [while trying to be as short as I can], kindly refer to
the timeline I made as it might help understanding the event chronologies easier.
OP made three accounts [well, actually four, and maybe more, but let's not dip our toe into that]. He asked for a ban on first account as his attempt to self-exclude. They didn't treat it as self-exclusion request as a few days later he asked for the ban to be lifted and they gave him six problematic gambling self-assessment questions, that he smoothly passed through dishonest answer. The first account later on requested for a ban-with-no-option-to-unban and OP did not use this account anymore. OP assumed this as a self exclusion. The casino did not, as there were no explicit words asking for it [regardless of what OP tried to counter-prove by series of chats to live support to validate this argument]. This is the same conclusion that's made by CG.
Now, move to the second account. On this account, OP lost 10,000+ USD, made a statement that triggered the problematic gambler alarm and kick the responsible gambling act to take action, blocking the account and officially [through casino's POV] marked OP as gambling addict. However, he managed to create third account, spent 508.72 USD, of which the casino admitted is their fault as the OP should have been excluded. Thus they're willing to reimburse. And thus, the amount.
The root of this situation is simple: OP treated his first plea to "ban with no option to unban" as a self exclusion. The casino simply treated it as a request to lock his account. Casino applied self-exclusion from the closure of second account forward, thus, third account will get reimbursed. OP insist self-exclusion should be activated from the point of "ban with no option to unban", thus his second account should not be allowed by Roobet, and is eligible for refund too.
