Let's see if I can make you get the situation here. You had several accounts which you denied their existence on the first place and only admitting it after they straightforwardly mentioned the names, this is understandably cast a huge doubt on your credibility. They've deemed this case closed, and your complain would as much turned to deaf ear.

The thing you can do right now is to raise an appeal to the community on this forum, prove that you're wrongly accused, and hope that sportsbet respected the forum and reopened your case for review. But so far, you've proven nothing other than repetitively stating that you didn't take any bonus, my long post of the inconsistencies of your statements are even only partially --and vaguely-- clarified, you hadn't provide the proof that I've asked several times: the proof of time gap between each of your accounts.

Let me try to break it down even further like I explaining to a third grader why this is quite important. On SB point of view, and as far as whoever read this thread understand, you created multi acc which violated their ToS. You argued back that the accounts are not active simultaneously, you've closed each of those account before opening a new one, which means you didn't have multi account and SB's accusation is invalid. But as I've pointed out --and marked in blue-- on previous post, you also agreed that they have the right to confiscate your fund if they suspected you registered multiple accounts in attempt to hide your betting activity or bypass their trading limit.

You stated that the reason why you opened and closed accounts are because you need a break after winning, but --again, as I've pointed out-- your statements during this entire case keeps contradicting each other, add that to the fact on your email screenshot that the date between those accounts are extremely close, it is very justified for anyone to think and suspected that there's another, more dubious, reason why you keep opening and closing accounts. You argued that those date didn't reflect on the real timespan between each account because it took a very long time for them to process account closure --oops, sorry, I was meaning to say "closing intervals for your 3 accounts are not very short"-- but you never give any concrete evidence to back up this claim, and I've asked you repetitively. If any, you just cast a bigger doubt on everyone's mind.

Let me try to break it down yet again, in a "flowchart".

You want them to give proof that you're wrongly accused? You'll want them to reopened your case. But how exactly do they reopen a case they considered closed? You'll need them to reconsider the case. And how exactly will they reconsider your case? Unfortunatelly, you can only hope they respected the forum's request and looked at your case again. So, up to this point, simplified, who you need to convince right now are the forum, i.e. the people reading this thread. You still following me? Good. So how exactly do you make the forum to do that? Well, sweetheart, this forum, especially people "overseeing" this sub-board are very fair and neutral. They judge everything by facts and data, evidences. If you've provide an undisputed evidences that you're the right side here, they won't be reluctant to support you. So what you need is to provide evidences instead of throwing tantrums and baseless statements.

Tl;dr: give your evidences.
