Accused of duplicated account without any proof to back it up

Hello,
My name is Pedro, i am here today to describe the issue i have been having with King Billy CASINO

--------- PROBLEM ----------
*King Billy Casino has confiscated all my gains of 1.650USD, accusing me of duplicated accounts and bonus abuse
*King Billy has provided NO PROOF of the accusation and has simply confiscated my gains of 1.650USD
*Every time King Billy support is asked to provied information they ignore me or give me a copy/paste answer of their rules about duplicate accounts and bonus abuses
*King Billy doesn't facilitate the direct contact with them, the only way i can actually talk with them is by live support or email(waiting 1-2 days for each of their answers)
*King Billy won't put me in direct contact with the financial department to see where is the problem or what is actually happening, neither will they answer the phone of their office
*King Billy has allowed me to withdrawl back my initial deposit of 350USD without even veryfing my account(which seems fishy for me)

---------- INTRODUCTION -----------
My first contact with them was at the 24th of september 2019, 2 days ago.
At the 24th of september i have already all the documents necessary to verify my account, as i am a regular player at N1 Casino and LaddyHammer. They are still pending.
After send my documents, i have done my first deposit with the welcome bonus, the amount of the deposit was of 250USD, which i lost wagering.
At the 25th of september i have done a second deposit aswell with the welcome bonus for the second deposit. Which i have completed the wager and finished my gaming with 2.000USD, this deposit was of 350USD.
I have streamed it all at my twitch channel, since the deposit until the moment i ask the withdrawl.
This morning i have waken up with my account showing a balance of 350USD, which is the value of my second deposit that i have completed the wager.
After contacting King Billy CASINO by the live support, as they wouldn't put me in contact with the financial by any ways, neither answer the phone of their office. I have been told that my gains were CONFISCATED, because they i have duplicated accounts and have abused the bonuses. Which is simply not true, and i can prove, different than them since every time i have asked them a proof showing that i actually have duplicated accounts they have straight up ignored me, IGNORED, absolutely no answers, besides one by email saying that "We don't need to provide this information as you have access to both accounts".
I CAN PROVE THAT I DO NOT HAVE DUPLICATED ACCOUNTS, AT ANY CASINO.
All my transactions from skill comes and goes to ONLY ONE place, the email registered at skrill, and my bank account in switzerland.
Different than them, i have showed nothing different than disposition to solve it in a good way. But KING BILLY CASINO treat me like nothing, simply not proving ANY KIND of proof to what they say.
Is this even real life? 2019 and people can simply come with whatever they want and confiscate your gains?

--------- FACTS ----------
* I have tried to solve it nicely but their support is simply awful
* I have never made any other deposits than these two showing at my account registered under pedro.m­az­zo@­hot­mai­l.com
* I can proof i do not have duplicated accounts
* King Billy rejects theirselves to send ANY KIND of PROOF to back up what they are accusing me for
* King Billy dificultates the direct contact with their company, giving you only the option to talk directly with the live support. They won't put you in contact with their "financial department", neitheir answer the phone of their office.
* My transactions from skrill goes only to this same email and to my swiss bank account
* I am a regular player at N1 CASINO, LADDY HAMMER. Never had any problems, went to play at king billy because they have good bonuses with lower wager and they accuse me of something not showing any proof to back up that.
* It's all recorded in my twitch channel. 9h to complete the wager, straight.
* They gave me back my initial deposit of 350USD even though they haven't verified my account. And confiscated my gains of 1.650USD without any proof to back up what i am being accused of.
* Taking a little look at the complaints on King Billy CASINO made here in askgamblers, you can see they are the type of company that are always looking for an excuse to difficultate withdrawls and such.

I can give pictures of whatever is needed for to solve this.
