JackpotCity complaint: Casino doing everything not to allow withdraw

The organizers of Jackpot city have used as an excuse the fact that I made a mistake in entering the wrong email address associated to my bank account to not give back the money that I had deposited in my account. They kept asking me to have the proof of a bank account associated with each of the email addresses, which was nonsense, as even if I explained it to them and I clearly told them many times it was a mistake asking for the withdrawal at the first address, as there was no bank account associated with it, they would continue asking for the bank account of the mistake email address. Right after I entered it, I instantly realized my mistake, I cancelled it and I put the correct one as I never did such transactions before, and it wasn’t so clear on the site, there was not a specification for ‘’Email address of your bank account’’ at the time instead it was ‘’Email address’’. I believed it was the email address of my casino account which wasn’t the same as the email of my bank. I have made a withdrawal of 812.80 and it was written that it was needed to make another deposit in order to make the withdrawal. I was naïve enough to deposit it, and I was still unable to withdraw the 800 which was now 805$ of my own stolen. That was a dishonest strategy and a proof that this organism is dishonest, I have the snapshot of it.
The client service told that they would transfer my situation to the superior level and did, but I had no reply. During this long verification a bug happened on my computer, the file containing the password of my JackpotCity casino account and of my email associated with it became corrupted as I transferred it (cut paste) on my external hard drive. This was an issue with Microsoft but they couldn’t help, they didn’t even wanted to give a way to access back my email address linked to my casino account manually as the recovery system didn’t worked. They were asking for the title of sent and received emails; this email was newly created to help me control myself whether I wanted to lock the password of the email and of my casino account in a box hidden in my things and give the key to my mother. There was no sent emails nor did I noted any title of email. They told me many times they will be following up with the superior levels and contact me back, but I never received anything of their words. A while after, I contacted them again and they transferred me the email they have sent to my void email address, asking for the same documents I have already sent them, and not answering to the explanations or questions I have asked them.
My bank account, credit card statements, driving license submitted as the same of the one I had already sent (which they said they have lost) was sufficient proof that it was me including the explanation and the exact amount of the last deposits.
I believe this is a case of theft as the casino has no right to not give back the money that I haven’t lost playing and even won a little more (817.80 – 805 initial deposit). An honest casino would not have taken it and kept it like that. I have sent a complaint contacting the support of Jackpotcity and they never replied to it, neither did they give a reference number. I have proof of all this. Thank you and I hope we can solve this as this is very depressing and not correct.
