I don't think it's 13533 wagers. I think it's 13533 wagered amount.
It’s clearer now since I read their reply (could be from a rep too) where they mentioned you deposited $200 and wagered 13,533, without the "$" sign. That’s why I’m assuming it triggered the system to flag your account for using a bot.
He then deposited $200 in ETH, used the bot, and wagered 13,533 within 20 minutes and quickly initiated a withdrawal to exit.
So if I bet $50 10 times then it's $500. The timestamps would be pretty clear about this once you see them.
Here's a screenshot I had before they banned. I have 437 pages so in total that is 4370 bets with 10 bets per page and look at the times though it doesn't seem to be sorted if you look at the ID you'll see that I really don't have that many.
https://i.ibb.co/WK0wkWP/bets.pngLooks like you’ve got a solid case here, since the casino’s claim of "Unusual Activity within 20 Minutes" doesn’t really come with clear proof of what kind of unusual activity they’re referring to. Starting with a $200 deposit and making a total of 13,533 wagers ($) is totally possible.
