Can somebody from Shuffle, or affiliated with Shuffle ask them what they still need from me in order to let me withdraw my deposit, like promised?
You can find their ANN thread on the forum.
What I stumble upon is about they say "they recognized my betting pattern (betting on same sports and same casino games like my first account)." I just barely know that the site or casino is able to detect pattern

that just insane frenn.
You said that you are use 2 different account with 2 different id with 2 different laptop but they still know about it just marvelous in my opinion. Are they using AI or some sort
He could have used the same Wi-Fi connection for both laptops or used the same payment information. The the chances of cheating a casino successfully is very slim because there are sophisticated ways casinos use to fish out multi accounts that we may not know.
